Gentoo on ZFS with native encryption on Root, TPM2 and per-user YubiKey

This page describes my personal steps of installing Gentoo on ZFS with native encryption on root enabled, TPM2 and per-user YubiKey support.

TODO

  • Add support for unlocking home directory using the fingerprint scanner as main or/and alternative - right now that is not important.

Hardware: XMG Ultra 17

Requirements

  1. Time and a little bit knowledge
  2. Bootable Live Unix-based distro with ZFS support (like nchevsky/systemrescue-zfs)
  3. YubiKey (at least 2 for backup)
  4. Device with TPM2
  5. Internet connection

Preparing live environment

Boot to the image and setup the environment as follow:

root #setkmap
root #timedatectl set-timezone Europe/Berlin
root #timedatectl set-ntp true
root #zgenhostid $(hostid)
root #echo $((2 * 1024 * 1024 * 1024)) > /sys/module/zfs/parameters/zfs_arc_min
root #echo $((8 * 1024 * 1024 * 1024)) > /sys/module/zfs/parameters/zfs_arc_max
root #mkdir -p /{etc/zfs, mnt/gentoo}

Disk layout

NVME drives will be used as ZFS pools without partition. SATA drives will contain 3 partitions: EFI (512 MiB), SWAP (32 GiB) and remaining space will be assigned for the ZFS pool.

EFI (512 MiB available)

First partition of SATA #1 and SATA #2 will represent the EFI partition and mirrored.

root #mkfs.vfat -F32 /dev/md127

ZPOOL (1.33 TiB available)

First partition of NVME #1 and NVME #2 will be in RAID 1 and the third partition of SATA #1 and SATA #2 will be also in RAID 1. All partition mentioned will be used to create a single mirrored ZPOOL.

root #zpool create -o ashift=12 -o cachefile="/etc/zfs/zpool.cache" -o autotrim=on -o autoexpand=on -O mountpoint=none -O canmount=off -O compression=zstd -O xattr=sa -O relatime=on -O atime=off -O acltype=posix -O dnodesize=auto -O normalization=formD -O devices=off -O setuid=off -O exec=off -m none -R "/mnt/gentoo" "rpool" mirror ${NVME_DISK1} ${NVME_DISK2} mirror ${ATA_DISK1}-part3 ${ATA_DISK2}-part3

SWAP (64 GiB available)

Second partition of SATA #1 and SATA #2 will be used as is to create SWAP partition.

User data datasets

/home/theaifam5
root #zfs create -o canmount=noauto -o mountpoint="/home/theaifam5" -o encryption=on -o keyformat=passphrase -o keylocation=prompt -o exec=on rpool/USERDATA/theaifam5
/var/db/repos/theaifam5 - optional
root #zfs create -o mountpoint="/var/db/repos/theaifam5" -o exec=off rpool/USERDATA/theaifam5/portage

Dataset structure verification

You might want to verify the structure of created datasets:

root #zfs list -o name,used,available,mountpoint,canmount,sync,utf8only,encryption,mounted,exec,setuid,devices,com.sun:auto-snapshot

Export ZFS pool:

root #zpool export rpool

Re-import ZFS pool and load keys:

root #zpool import -R "/mnt/gentoo" rpool
root #zfs load-key rpool/ROOT
root #zfs load-key rpool/USERDATA/theaifam5

Afterwards you can mount the home directory from the userdata dataset:

root #zfs mount rpool/ROOT
root #zfs mount rpool/USERDATA/theaifam5
root #zfs mount -a

Extraction and setup

First of all, we need to extract the Gentoo onto ZFS, it might take a while:

root #tar xpf /tmp/stage3.tar.xz --xattrs-include='*.*' --numeric-owner -C /mnt/gentoo

Afterwards we can create an EFI directory and mount it:

root #mkdir -p /mnt/gentoo/boot/efi
root #mount /dev/md127 /mnt/gentoo/boot/efi

Also ZFS Cache file, resolv.conf and hostid needs to be copied:

root #mkdir -p /mnt/gentoo/etc/zfs
root #cp /etc/zfs/zpool.cache /mnt/gentoo/etc/zfs/zpool.cache
root #cp --dereference /etc/resolv.conf /mnt/gentoo/etc/resolv.conf
root #cp /etc/hostid /mnt/gentoo/etc/hostid

Chrooting

Everything should be prepared now, we can chroot into the environment using:

root #mount --rbind /dev /mnt/gentoo/dev
root #mount --rbind /proc /mnt/gentoo/proc
root #mount --rbind /sys /mnt/gentoo/sys
root #mount --make-rslave /mnt/gentoo/dev
root #mount --make-rslave /mnt/gentoo/proc
root #mount --make-rslave /mnt/gentoo/sys
root #test -L /dev/shm && rm /dev/shm && mkdir /dev/shm
root #mount --types tmpfs --options nosuid,nodev,noexec shm /dev/shm
root #chmod 1777 /dev/shm
root #env -i HOME=/root TERM=$TERM chroot /mnt/gentoo bash

Now, just setup the chrooted environment:

(chroot) rootsource /etc/profile
(chroot) rootenv-update
(chroot) rootexport PS1="(chroot) ${PS1}"

Installation

Base System

Select the default gentoo repository, it will fetch the state of the last 24 hours

(chroot) rootmkdir -p /etc/portage/{repos.conf,package.{use,mask,unmask,provided}}
(chroot) rootcp /usr/share/portage/config/repos.conf /etc/portage/repos.conf/gentoo.conf

You might want also to update to the newest but only if is required:

(chroot) rootemerge --sync
