  • [gentoo-user] ISO on /boot

    From Peter Humphrey@21:1/5 to All on Tue Apr 12 13:10:01 2022
    Hello list,

    I've seen people say they have a rescue ISO image in their /boot partition.
    I'd like to try this; is there any particular knack to it, or do I just copy the ISO image into place? I'm using bootctl from sys-boot/systemd-boot.

    Unlike GRUB, systemd-boot doesn't have the ability to boot directly from
    an ISO image (GRUB can mount the ISO) but if you are using System Rescue,
    you can mount the mage and copy the relevant files to /boot. Full
    instructions are on the System Rescue site, here the the boot loader
    entry I use

    title System Rescue 9.01
    version 9.01
    linux /sysresccd/boot/x86_64/vmlinuz
    options archisobasedir=sysresccd archisolabel=boot setkmap=uk rootpass=password1
    initrd /sysresccd/boot/x86_64/sysresccd.img

    You need to set a filesystem label on /boot and use that for the archisolabel argument.

    There is absolutely no substitute for a genuine lack of preparation.

    Just what I needed. Thanks Neil
