Note
If you're looking for a general purpose how to install Gentoo guide, without opinions (e.g., no FDE, no desktop profile w/ systemd) you can follow the Official Installation Guide. It's also the best place to go if anything breaks here!

This guide will walk you through an installation of Gentoo using the Asahi Linux patchset. The current supported distribution by Asahi Linux is Fedora. Due to macOS not allowing USB devices for booting, we're going to use "asahi-gentoosupport" to boot Gentoo off of an initramfs to mimic a liveusb.

This guide will end up creating an encrypted root partition (which prevents someone from accessing your data through single user mode) with Gentoo Linux on it.

Preparing Asahi Linux (Fedora)

Before we can get into Gentoo, we'll need to use the Asahi Linux installer to setup everything for us. Before running the following, it's highly recommended that you read the script at https://alx.sh, since piping to sh is generally a bad practice. For ease, we'll do that anyways.

The installer needs to run as root. Please enter your sudo password if prompted. Password: enter your user's password then Enter

Welcome to the Asahi Linux installer!

This installer will guide you through the process of setting up Asahi Linux on your Mac.

Please make sure you are familiar with our documentation at:

 https://alx.sh/w

Press enter to continue. press Enter

By default, this installer will hide certain advanced options that are only useful for Asahi Linux developers. You can enable expert mode to show them. Do not enable this unless you know what you are doing. Please do not file bugs if things go wrong in expert mode. » Enable expert mode? (y/N) press y then Enter

Press enter to continue. press Enter


When the system shuts down, follow these steps:

1. Wait 15 seconds for the system to fully shut down. 2. Press and hold down the power button to power on the system.      * It is important that the system be fully powered off before this step,        and that you press and hold down the button once, not multiple times.        This is required to put the machine into the right mode. 3. Release it once you see 'Entering startup options' or a spinner. 4. Wait for the volume list to appear. 5. Choose 'Gentoo'. 6. You will briefly see a 'macOS Recovery' dialog.      * If you are asked to 'Select a volume to recover',        then choose your normal macOS volume and click Next.        You may need to authenticate yourself with your macOS credentials. 7. Once the 'Asahi Linux installer' screen appears, follow the prompts.

If you end up in a bootloop or get a message telling you that macOS needs to be reinstalled, that means you didn't follow the steps above properly. Fully shut down your system without doing anything, and try again. If in trouble, hold down the power button to boot, select macOS, run this installer again, and choose the 'p' option to retry the process

Press enter to shut down the system. DO NOT PRESS ENTER. Continue reading the doc

Finishing the Asahi Linux Install

We're now close to having an Arch Linux install! The next step is to reboot. As you may have noticed from the output, there's an amount of complexity to the next steps, so please read the below carefully. When you reboot the computer do the following steps:

  1. Wait 15 seconds.
  2. Press and HOLD the power button until you see "Entering startup options" or a spinner.
  3. Release the power button (if you haven't already)
  4. Wait for "Gentoo" to appear. Choose 'Gentoo' using the arrow keys, select it and press Enter
  5. You will see what appears to be a macOS Recovery screen. Enter your user's password, if prompted (usually if FileVault is enabled).

If all went well, a terminal window should appear. This will set your system into permissive mode to allow booting Linux.

Note
The Asahi Linux devs are working on removing this requirement. If you have File Vault enabled, your credentials will always be required to install a new operating system, like we just did, which makes your system still secure against malicious actors. If you do not have File Vault enabled, the author recommends doing so

Follow the instructions on terminal window, it will mostly just consist of pressing Enter and at the end entering the username and password of your macOS user. At the end it'll ask you if you'd like to reboot, press Enter to do so an you'll be presented with the output of U-Boot. U-Boot is used as the bootloader, which right now just chains Grub (which most users should be familiar with). Grub, in turn, boots into Fedora for us. If all went well, you should see a TTY asking you a lot of questions. On to the next step!

Configuring Asahi Linux

In order to create our Gentoo "liveusb" (powered by an initramfs), we'll need to update the system first to ensure that we don't run into issues later. We're going to do this by running "dnf", the Fedora package manager. However, first we'll need to go through the configuration steps.

1) [ ] Language Options           2) [x] Time Settings
3) [x] Network Configuration      4) [!] Root password
5) [!] User Creation
Please make a selection from the above ['c' to continue, 'q' to quit', 'r' to
refresh]:
press 4 then Enter
Please select new root password. You will have to type it twice:

Password:
enter a root password then Enter
Password (confirm):
enter the same password again then Enter
1) [ ] Language Options           2) [x] Time Settings
3) [x] Network Configuration      4) [x] Root password
5) [!] User Creation
Please make a selection from the above ['c' to continue, 'q' to quit', 'r' to
refresh]:
press q then Enter
Are you sure you want to quit the configuration process?
  You might end up with unusable system if you do.
Please respond 'yes' or 'no':
refresh]: 
enter "yes" then Enter

You should now have a TTY screen, where you can enter "root" and the password you selected earlier!

To connect to wifi, we're going to use NetworkManager. We'll do this through the nmcli command.

[root@fedora ~]#nmcli device wifi connect <ssid> password <password>

Let's validate that our network connectivity is working as expected

[root@fedora ~]#reboot

Setting up the Gentoo "liveusb"

Now we can use asahi-gentoosupport to create the initramfs-based liveusb. We'll need to download git to clone the repo and wget to fetch the latest minimal iso.

[root@alarm ~]#dnf install git wget

From there, clone the repository and change into the newly created directory.

[root@alarm ~]#cd asahi-gentoosupport

In order for us to be able to run the genstrap.sh script, we'll need to download the latest install minimal iso for our platform. For convenience, I've written a script to automate fetching the latest minimal ISO. I highly encourage reading through the script before running it!

When rebooting your system, select Gentoo Live Install environment from
the GRUB menu to boot into the Gentoo LiveCD.

We now have an entry in our Grub menu titled "Gentoo Live Install Environment". When selected, it will use our current kernel to boot an initramfs that contains the contents of the minimal install iso we downloaded earlier. This allows us to customize the partition that we're currently booted on. Namely, this allows us to wipe away Arch Linux (Asahi) and replace it with an encrypted Gentoo installation. Next we'll reboot and select the "Gento Live Install Environment" option from Grub so we can start the Gentoo install!

[root@fedora asahi-gentoosupport]#reboot

Wait for u-boot to send you into Grub, then select the "Gentoo Live Install Environment" option. You should see a number of penguins at the top of the screen, with dmesg output scrolling across the screen. Finally, you should be dumped into the familiar livecd ~ output of a Gentoo minimal install USB!

Setting up Networking (again)

Now that we're in a Gentoo install environment, we're going to need network connectivity again. This time, we're going to use net-setup. This will open a terminal UI that will ask you questions about your network setup. Follow the interactive prompts as needed. Once finished, run ifconfig until you have an ip address for your network interface (it may take a little bit!).

livecd ~ #ifconfig | grep w -A 2 | grep "inet "
    inet 192.168.1.250  netmask 255.255.255.0  broadcast 192.168.1.255
Note
If you're not getting an ip address and you're sure that you're entering the correct wireless credentials, check if your SSID is WPA3. Some settings may not be supported in this minimal installation environment. Use a 2.4 ghz network if possible, in this case.

Once again, let's double check that our network is working as expected.

(Optional) Setup SSH

It can be helpful to do the next step over SSH from a second "helper" computer, since a lot of the next steps may require a lot of copy and pasting as well as typing, which can be not very fun on a TTY session.

To setup ssh we'll need to set a password for root and start the SSH daemon.

livecd ~ #/etc/init.d/sshd start
livecd ~ #passwd root

Using the IP address from earlier, connect to your machine over SSH.

user $ssh root@192.168.X.X

Now you can continue with the rest of the guide over SSH (until you reboot, anyways!)

Preparing the Filesystem

This section shadows Chapter 4 of the Gentoo Handbook, so please give that a read if you have any questions about what is going on here. It goes into much better detail about disk setup, in general, than I could ever do myself.

We're going to setup a LUKS2 encrypted volume using cryptsetup, from there we're going to create a btrfs formatted partition to be our root partition. Advanced users can setup LVM here, if they wish, but this is out-of-scope of this tutorial (the author doesn't believe LVM provides much value in today's world).

Let's start by identifying our disks. Thankfully, as of this writing, you can easily find the partitions by their labels. Let's used blkid to find them.

livecd ~ #blkid --label fedora
livecd ~ #blkid --label "EFI - GENTO"
/dev/nvme0n1p5 # asahi-root
/dev/nvme0n1p4 # EFI - GENTOO

The asahi-root partition is our / partition, while the EFI - GENTO partition will be our /boot partition.

Important
Do not mess with the boot partition, doing so may break the entire install.

Make note of the asahi-root device path, it will be used for our next command, when we use cryptsetup to create our encrypted partition. Using cryptsetup, we're going to create an encrypted partition, first lets dig into the arguments that we're going to be using.

  • We use argon2id instead of PBKDF because it is more resistant to ASIC/GPU cracking. We do not bump the iterations because [it is generally not worth the cost compared to using a higher entropy passphrase].
  • We keep the default of using aes-xtc because it is better supported and accelerated by hardware (yes, even the M1 mac has the aes CPU feature).
  • We use luks2 because we are not using Grub to boot our kernel (no encrypted /boot) and it provides better security tooling, such as cryptsetup reencrypt.


livecd ~ #cryptsetup luksFormat --type luks2 --pbkdf argon2id --hash sha512 --key-size 512 /dev/nvme0n1p#
WARNING: Device /dev/nvme0n1p# already contains a 'ext4' superblock signature.

WARNING!
========
This will overwrite data on /dev/nvme0n1p5 irrevocably.

Are you sure? (Type 'yes' in capital letters) <type YES>

This will take a little bit, cryptsetup will optimize the amount of iterations and memory to use based on how many it can do in 2 seconds to ensure the most secure, but also reasonable, options are set for your system.

Once that's finished, we can take a look at what it did by using the cryptsetup luksDump command. Let's take a look.

livecd ~ #cryptsetup luksDump /dev/nvme0n1p#

        Iterations: 422132
        Salt:       <snipped hex>
        Digest:     <snipped hex>

Next, we're going to mount the device as a mapper device that will enable us to treat the luks device as an unencrypted device for formatting.

livecd ~ #cryptsetup luksOpen /dev/nvme0n1p# luks
Enter passphrase for /dev/nvme0n1p#: <type in your password then press ENTER>

This mounted our luks device as a path at /dev/mapper/luks (based on the last argument to the command) that we'll use as our root device for creating a btrfs partition.

Note
Advanced users can replace btrfs with their preferred filesystem, but be sure to update/research areas that it needs to be included in when mentioned later.
livecd ~ #mkfs.btrfs --label root /dev/mapper/luks

We now have a btrfs disk that we can mount and start our installation of Gentoo on. We're going to use a stage-3 archive to create an installation of Gentoo. A stage-3 is essentially a minimal installation, but with no kernel. Only libraries and binaries that are required to bootstrap a Gentoo installation. Let's mount the file system and download the stage-3 archive.

livecd ~ #mkdir --parents /mnt/gentoo
livecd ~ #mount /dev/mapper/luks /mnt/gentoo
livecd ~ #cd /mnt/gentoo

Now we'll download the stage-3 archive, we'll need to get the latest version first. Just like downloading the minimal install ISO earlier, we're going to use a helper script (that you should read first!).

Sccessfully validated image.
Image is available at: /mnt/gentoo/latest-stage3-arm64-desktop-systemd.tar.xz

Now we're going to extract the contents of the archive into our directory, thus creating the Gentoo install.

livecd /mnt/gentoo #tar xpvf latest-stage3-arm64-desktop-systemd.tar.xz --xattrs-include='*.*' --numeric-owner

As per the handbook, the options to tar are to extract, provide verbose output, decompress with xz (J), preserve permissions and extract from a file, not standard input. Further, the --xattrs-include='*.*' option ensures that extended attributes stored in the tarball are also copied (from all namespaces), and the --numeric-owner option uses the numeric owner and group IDs from the tarball, even if they are different in the host system (they will not be here, since we are booted from an official minimal install image, but it doesn't hurt to specify this).[1]

Let's make sure that the base system installed OK

livecd /mnt/gentoo #ls
bin   dev  home  lib64  mnt  proc  run   stage3-arm64-desktop-systemd-20230514T223201Z.tar.xz      sys  usr
boot  etc  lib   media  opt  root  sbin  stage3-arm64-desktop-systemd-20230514T223201Z.tar.xz.asc  tmp  var

If you see output similar to the above, you should be good to go!

Before we continue, you may want to read up on portage, emerge, and other aspects of Gentoo package management[2]. We'll wait for you, don't worry! :)

Creating a chroot

Now that we have a Gentoo system, let's chroot into it so we can install the required packages as well as do initial configuration of our shiny new system.

To start with, we're going to opt into the Gentoo package repository.

livecd /mnt/gentoo #mkdir --parents /mnt/gentoo/etc/portage/repos.conf
livecd /mnt/gentoo #cp /mnt/gentoo/usr/share/portage/config/repos.conf /mnt/gentoo/etc/portage/repos.conf/gentoo.conf

From there we need to ensure that networking still works from inside of the chroot.

livecd /mnt/gentoo #cp --dereference /etc/resolv.conf /mnt/gentoo/etc/

Now.. the exciting part (or for those of us who have ran through 'many gentoo installs, the tedious part). We're going to mount the required devices from the host into the chroot so that everything still works as expected from inside the chroot.

livecd /mnt/gentoo #mount --types proc /proc /mnt/gentoo/proc
livecd /mnt/gentoo #mount --rbind /sys /mnt/gentoo/sys
livecd /mnt/gentoo #mount --make-rslave /mnt/gentoo/sys
livecd /mnt/gentoo #mount --rbind /dev /mnt/gentoo/dev
livecd /mnt/gentoo #mount --make-rslave /mnt/gentoo/dev
livecd /mnt/gentoo #mount --bind /run /mnt/gentoo/run
livecd /mnt/gentoo #mount --make-slave /mnt/gentoo/run

Whew. That was exciting... let's enter the chroot and mount the our /boot partition from earlier! While we're here, we're going to change our PS1 (terminal prompt) to convey that we're in a chroot. This helps make it easier to remember that we're in a chroot vs the live usb image.

livecd /mnt/gentoo #chroot /mnt/gentoo /bin/bash
livecd /mnt/gentoo #. /etc/profile
livecd /mnt/gentoo #mount /dev/nvme0n1p# /boot # The "#" number is partition number from 'blkid --label "EFI - GENTO"' earlier!

Now we're in our future Gentoo system! Let's go ahead and do some basic setup to ensure that we have a functional system, plus some steps exclusive to the M1 mac :)

Configuring the Basics

The first thing to setup in any Gentoo system is portage. This will allow us to configure how things are compiled and with what flags. We're going to use a stock configuration created by the author -- since it works out of the box with M1 macs. Feel free to change it as needed.

FILE /etc/portage/make.conf
# vim: set language=bash;
CHOST="aarch64-unknown-linux-gnu"

# Optimization flags.
COMMON_FLAGS="-march=armv8.5-a+fp16+simd+crypto+i8mm -mtune=native -O2 -pipe"
CFLAGS="${COMMON_FLAGS}"
CXXFLAGS="${COMMON_FLAGS}"
FCFLAGS="${COMMON_FLAGS}"
FFLAGS="${COMMON_FLAGS}"
RUSTFLAGS="-C target-cpu=native"

# This sets the language of build output to English.
# Please keep this setting intact when reporting bugs.
LC_MESSAGES=C

# Note: Update "-j" to be a number more appropriate for your
# hardware (e.g., m2 max has more cores).
MAKEOPTS="-j4"

# GENTOO_MIRRORS is the mirrors to use for emerge sources. The author
# hosts one on R2, which should be fast enough for most usecases.
GENTOO_MIRRORS="https://gentoo.rgst.io/gentoo"

# EMERGE_DEFAULT_OPTS is the options to use for emerges. We use -j3 here to
# enable compiling at most 3 packages at the same time. This also makes logs not spam
# our screen everytime. It's nice :)
EMERGE_DEFAULT_OPTS="--jobs 3"

# VIDEO_CARDS is the video card (gpu) we're using. We use "asahi" for the mesa package provided
# by the asahi-overlay.
VIDEO_CARDS="asahi"

# Keep a newline at the end! Important!

For brevity, we'll download this one from the Github Gist, feel free to check it out to see if any changes have been made since the writing of this post.

Now we'll need to fetch the packages available from the Gentoo repositories, the first time can take a really long time, so we use emerge-webrsync to speed things up and reduce the load on the servers.

(chroot) livecd / #emerge-webrsync

Performing Global Updates
(Could take a couple of minutes if you have a lot of binary packages.)

 * IMPORTANT: 11 news items need reading for repository 'gentoo'.
 * Use eselect news read to view new items.

Note
Ignore any warning that looks like the below
!!! Section 'gentoo' in repos.conf has location attribute set to nonexistent directory: '/var/db/repos/gentoo'
!!! Invalid Repository Location (not a dir): '/var/db/repos/gentoo'
This will be solved by the command that was just ran, as it will create that directory.

Now that we've established the repository from a web snapshot, we're going to wait to do what we'd normally do to update the repository package list.

(chroot) livecd / #emerge --sync
>>> Syncing repository 'gentoo' into '/var/db/repos/gentoo'...
 * Using keys from /usr/share/openpgp-keys/gentoo-release.asc

>>> Starting rsync with rsync://[2a00:1828:a00d:ffff::6]/gentoo-portage...
>>> Checking server timestamp ...
... lots of output snipped ...

It's a good idea to ensure that portage itself is up-to-date, though it should be if you downloaded a new snapshot :)

(chroot) livecd / #emerge --ask --verbose --oneshot portage
... output omitted ...
Would you like to merge these packages? [Yes/No] <press Y and then ENTER>
... output omitted ...

You may have noticed a lot of "IMPORTANT" news items. This is a great system provided by Gentoo repositories for communicating changes, however as this is your first time pulling them down, it will be showing things even years old that don't really apply to us. However, it's still worth taking a look! You can list all of the news items through eselect news list and read an individual item with eselect news read #.

For now, let's clear them so we can start fresh (unless you see something really scary in there from after this guide's last updated date at the top of this guide!).

(chroot) livecd / #eslect news read

Let's go ahead and update @world, this is useful because of all of that changes that we made to our /etc/portage/make.conf file earlier.

(chroot) livecd / #emerge --ask --verbose --update --deep --newuse @world
... output omitted ...
Would you like to merge these packages? [Yes/No] <press Y and then ENTER>
... output omitted ...

This will take a little bit, but also be your first taste (aside from updating portage earlier) of using emerge. This is how we'll update our system in the future as well, so take note of those flags!

Our next step is configuring the system to our liking, the basics of any Gentoo installation. We're going to setup the localtime, our locale, and create ourself a user (because running as root is bad!)

Setting a Timezone

Let's start by picking a local timezone, for the author we'll use America/Los_Angeles, so replace that with whatever your timezone is.

(chroot) livecd / #ln -sf /usr/share/zoneinfo/America/Los_Angeles /etc/localtime

Picking a Locale

Now we'll pick our locale, open the file up with your favorite editor (nano is the easiest for newcomers!).

(chroot) livecd / #nano -w /etc/locale.gen

Uncomment, or if not present replace, your locales. For the author, it would be:

FILE /etc/locale.gen
en_US ISO-8859-1
en_US.UTF-8 UTF-8

Then, make sure to run locale-gen to generate the required locales.

(chroot) livecd / #locale-gen
 * Generating 3 locales (this might take a while) with 8 jobs
 *  (1/3) Generating en_US.ISO-8859-1 ...                                                                              [ ok ]
 *  (3/3) Generating C.UTF-8 ...                                                                                       [ ok ]
 *  (2/3) Generating en_US.UTF-8 ...                                                                                   [ ok ]
 * Generation complete
 * Adding locales to archive ...

Now we'll need to pick our default locale, which we can do with eselect locale list.

(chroot) livecd / #eselect locale list
Available targets for the LANG variable:
  [1]   C
  [2]   C.utf8
  [3]   POSIX
  [4]   en_US
  [5]   en_US.iso88591
  [6]   en_US.utf8
  [7]   C.UTF8 *
  [ ]   (free form)

Pick the locale option that is a UTF-8 option. So, for the author it is en_US.utf8.

(chroot) livecd / #eselect locale set 6
Setting LANG to en_US.utf8 ...
Run ". /etc/profile" to update the variable in your shell.

As it suggests, we'll need to resource /etc/profile for it to take effect.

(chroot) livecd / #env-update && . /etc/profile && export PS1="(chroot) $PS1"
>>> Regenerating /etc/ld.so.cache...

Now we're ready to create a user!

Creating a User

Let's go ahead and create a user for us to use, in the future. Decide on a username and use in the <username> fields in the command below.

(chroot) livecd / #useradd <username>
Creating mailbox file: No such file or directory
Note
If you see the below:
Creating mailbox file: No such file or directory
Feel free to ignore it, we don't need to worry about mailbox support right now.

Now we'll set a password for our user and then the root user as well, in case of any issues when we reboot later it's helpful to have that set.

(chroot) livecd / #passwd <username>
(chroot) livecd / #passwd # Root user!
Enter new password:
Re-type new password:
passwd: password updated successfully
# Root!
Enter new password:
Re-type new password:
passwd: password updated successfully

That's it for the basics! Now we can get started on building our own Kernel.

Building the Kernel

Currently, we'll build everything as normal through asahi-gentoosupport and then use the asahi-kernel package. To do so, we'll need to emerge the git package.

(chroot) livecd / #emerge --ask --verbose dev-vcs/git
... output omitted ...
Would you like to merge these packages? [Yes/No] y
... output omitted ...

Let's clone the repository again, since it's long gone from our Arch partition from earlier

(chroot) livecd / #cd asahi-gentoosupport
Cloning into 'asahi-gentoosupport'...

Resolving deltas: 100% (144/144), done.

Now we can run the install.sh script to take care of installing a dist-kernel and other required packages through the sys-apps/asahi-meta package.

(chroot) livecd /asahi-gentoosupport #./install.sh

.. emerge output snipped ...

Note: I had to run emerge -1 --autounmask-write sys-apps/asahi-meta and then dispatch-conf to get packages to actually install. Afterwards, you can re-run install.sh. This may not be required, but if you see a warning about "USE changes required", you'll need to do the same.

We have a Kernel now! Next, we'll configure dracut to build a crypto friendly initramfs and install iwd so we can reach the internet when we reboot.

Setting up the initramfs

In order to setup our initramfs, we're going to need two UUIDs. We'll need the PARTUUID (NOT the UUID!) of the LUKS (encrypted) partition we made as well as the UUID of the btrfs volume. Lets use blkid to get them.

(chroot) livecd /asahi-gentoosupport #blkid $(blkid --label root) # We want "UUID", we will refer to as "btrfs UUID"
/dev/mapper/luks: LABEL="root" UUID="86a9b8cd-e939-490c-9203-05ebb07c0217" UUID_SUB="c4a82413-e29e-429f-8e18-62e0439c3e22" BLOCK_SIZE="16384" TYPE="btrfs"

Let's configure dracut to support luks, we'll do so by creating /etc/dracut.conf.d/luks.conf

(chroot) livecd /asahi-gentoosupport #mkdir --parents /etc/dracut.conf.d/
(chroot) livecd /asahi-gentoosupport #nano -w /etc/dracut.conf.d/luks.conf
FILE /etc/dracut.conf.d/luks.conf
# Note: GRUB will override kernel_cmdline, so do not set it!
kernel_cmdline=""
add_dracutmodules+=" btrfs systemd crypt dm "
install_items+=" /sbin/cryptsetup /bin/grep "
# Change this if you didn't use btrfs.
filesystems+=" btrfs "

Next we can update /etc/default/grub to contain the required kernel parameters.

(chroot) livecd /asahi-gentoosupport #nano -w /etc/default/grub
FILE /etc/default/grub
# rd.auto automatically discovers the encrypted LUKS partition
GRUB_CMDLINE_LINUX="rd.auto=1 rd.luks.allow-discards"
GRUB_DEVICE_UUID="<btrfs UUID>"

Next we'll update /etc/fstab. To do so, we'll need the UUID of the /boot partition. We'll get it with blkid again.

(chroot) livecd /asahi-gentoosupport #blkid $(blkid --label "EFI - GENTO") # We want "UUID", we will refer to as "boot UUID"
/dev/nvme0n1p4: LABEL_FATBOOT="EFI - GENTO" LABEL="EFI - GENTO" UUID="1C83-E48B" BLOCK_SIZE="4096" TYPE="vfat" PARTUUID="4ad6d68f-be3a-4dad-bb73-e250c08d1234"
(chroot) livecd /asahi-gentoosupport #nano -w /etc/fstab
FILE /etc/fstab
UUID=<btrfs UUID>         /               btrfs           rw,relatime,ssd,space_cache=v2,subvolid=5,subvol=/      0 0
UUID=<boot UUID>          /boot           vfat            rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,errors=remount-ro        0 2

In order to build the initramfs, we'll need to install a few things. Namely cryptsetup, grep and btrfs-progs. We will also install NetworkManager as well as sudo so we don't need to later.

(chroot) livecd /asahi-gentoosupport #emerge --ask --verbose net-misc/networkmanager sys-fs/cryptsetup sys-fs/btrfs-progs sys-apps/grep app-admin/sudo

Finally, we need to update systemd to support cryptsetup, which will be used by dracut for unlocking.

(chroot) livecd /asahi-gentoosupport #nano -w /etc/portage/package.use/fde
FILE /etc/portage/package.use/fde
sys-apps/systemd cryptsetup

Now we can build the initramfs, normally this would be just dracut --force, but for now we also need to specify the kernel version.

(chroot) livecd /asahi-gentoosupport #dracut --kver $(make -C /usr/src/linux -s kernelrelease) --force

We now have an initramfs that supports running decrypting our root device. At this point we can now reboot through the command reboot, or do some of the optional tasks(s) below.

(Optional) Setup Sudo

Open up /etc/sudoers through the command visudo and uncomment one of the optional rules for users in the group wheel.

(chroot) livecd /asahi-gentoosupport #visudo

Add your user to the wheel group.

(chroot) livecd /asahi-gentoosupport #usermod -aG wheel <your user>

Post-Install Steps

At this point you should have rebooted, or if not go ahead and do it now. If all went well, you should be looking at a prompt to unlock your device. Go ahead and type your password to do so. If you don't, or have some other issue, check out the "Troubleshooting" section of this guide.

At this point you can continue to customize your system as if it were a normal Gentoo machine. Users may want to look at the Handbook for next steps (ignore that it is amd64) Handbook:AMD64/Installation/Finalizing, you also may want to reference the standard Asahi Gentoo install guide that this is built on, namely the Maintenance section.

Troubleshooting

"Hangs" then eventually boots into Emergency Mode

There's something wrong with your dracut or grub cmdline configuration. You can escape the emergency shell by doing the following:

root #cryptsetup luksOpen /dev/nvme0n1p# luks
root #exit

Make sure to replace # with your partition for LUKS, you can use blkid to fetch it if needed.

Wi-Fi Firmware isn't Working

The /lib/firmware/vendor directory needs to exist for firmware setup to function (it silently fails right now).

root #mkdir /lib/firmware/vendor
root #exit
