Gentoo Minimal Install Image Now Supports UEFI Boot

Talk status

This discussion is done.

As of at least install-amd64-minimal-20180828T214505Z.iso, the Gentoo minimal install image now appears to support both UEFI and legacy boot (this is a relatively recent change, since e.g. install-amd64-minimal-20180703T214502Z.iso supported legacy boot only).

In light of this, I suggest the recommendation in this article, that "... Gentoo's Minimal Installation CD is not recommendable for Live USB, because it can't be booted from UEFI.", be dropped. --Sakaki (talk) 11:14, 30 August 2018 (UTC)

Sounds like a good plan. I haven't personally tested the new LiveCD, but I've heard about UEFI support on new minimal LiveCDs... I should be able to test soon (perhaps even tonight). You should make the change. Thanks, Sakaki ! --Maffblaster (talk) 16:00, 30 August 2018 (UTC)

OK thanks, edit made! --Sakaki (talk) 18:15, 30 August 2018 (UTC)

SystemRescueCD no longer based on Gentoo

Talk status

This discussion is done as of 2019-03-07.

As of version 6.0.0 systemrescuecd is based on Arch Linux instead of Gentoo. Because of this I suggest removing the recommendation or at least adding a note informing the user of the switch. Thymo (talk) 16:16, 6 March 2019 (UTC)

Right. Added a note since version 5.3.2 might still be useful for a while until it becomes obsolete. — GuillermoDH (talk) 18:17, 7 March 2019 (UTC)

Outdated LiveDVD

Talk status

This discussion is done as of 2022-02-22.

Last LiveDVD iso file is 5 years old and was removed from g.o/downloads page. Is it safe to use it today or the recommendation should be removed? Szymon Scholz (talk) 06:12, 13 April 2021 (UTC)

The article no longer mentions the LiveDVD, closing. Can't comment on if old images should still be used, but I don't think they are available for download anymore. There may be a new "LiveDVD" some day. -- Ris (talk) 10:01, 22 February 2022 (UTC)

Gentoo Minimal Install ISO doesn't use ISOLINUX anymore

Talk status

This discussion is still ongoing.

The article (chapter "Creating bootable LiveUSB drives from Linux systems") assumes that the ISO uses ISOLINUX bootloader and provides instructions/scripts on how to convert it to SYSLINUX for use on USB drives. However, it seems both the Minimal ISO and Admin ISO use GRUB 2, so the instructions/script may not work as intended:

user $bsdtar -tf install-amd64-minimal-20230122T154655Z.iso | grep -i -e grub.cfg -e isolinux -e syslinux

boot/grub/grub.cfg
boot/grub/i386-efi/syslinuxcfg.mod
boot/grub/i386-pc/syslinuxcfg.mod
boot/grub/x86_64-efi/syslinuxcfg.mod

It seems likes ISOLINUX was replaced with GRUB 2 back in 2020: [0a27a7a3 targets: Use GRUB for BIOS boot], so this has been likely broken for quite a while. --Ahippo (talk) 03:36, 29 January 2023 (UTC)

My use case was to modify default boot parameters, which I think I managed to do by extracting the ISO (make sure to copy .disk/ directory too -- it's needed to boot in UEFI mode), editing boot/grub/grub.cfg as needed, and using the following to regenerate the ISO with my changes (this is what Catalyst does these days) (which can then be copied to a USB stick with dd):

user $grub-mkrescue -joliet -iso-level 3 -o my-install-amd64.iso gentoo-cd/
