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Outdated LiveDVD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 done as of 2023-07-20.

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/
--Ahippo (talk) 03:58, 29 January 2023 (UTC)
Indeed the minimal ISO uses grub2 boot. I was able to create to create a bootable LiveUSB without having to reorder any files and without adjusting the syslinux configuration file
--Josh (talk) 19:51, 16 April 2023 (UTC)
I have moved the ISOLINUX parts under LiveUSB/ISOLINUX and marked it with a warning, since it is no longer relevant to contemporary Gentoo live images. --Maffblaster (talk) 05:50, 21 July 2023 (UTC)
