    Dear initramfs-tools Maintainers,

    while investigating Grml Live build (*) failures, I came across these
    error messages:

    Setting up linux-image-6.12.17-arm64 (6.12.17-1) ...
    I: /vmlinuz.old is now a symlink to boot/vmlinuz-6.12.17-arm64
    I: /initrd.img.old is now a symlink to boot/initrd.img-6.12.17-arm64
    I: /vmlinuz is now a symlink to boot/vmlinuz-6.12.17-arm64
    I: /initrd.img is now a symlink to boot/initrd.img-6.12.17-arm64 /etc/kernel/postinst.d/initramfs-tools:
    update-initramfs: Generating /boot/initrd.img-6.12.17-arm64 /usr/sbin/mkinitramfs: 122: cannot open /sys/module/firmware_class/parameters/path: No such file
    /usr/sbin/mkinitramfs: 122: cannot open /sys/module/firmware_class/parameters/path: No such file
    /usr/share/initramfs-tools/hooks/live: 122: cannot open /sys/module/firmware_class/parameters/path: No such file

    sed: can't read /proc/cmdline: No such file or directory

    grep: /proc/cpuinfo: No such file or directory

    Especially the lines marked "mkinitramfs: 122" seem to make no
    sense, as /usr/sbin/mkinitramfs line 122 does not seem to deal with /sys/module/firmware_class/parameters/path at all.

    It would be nice if this could be improved.

    Chris


    (*) these builds run containerized and thus do not have /sys or
    /proc. This configuration may be unusual, but works fine in
    practice, or least did until initramfs-tools 0.146.
    It has the advantage of not leaking system state from the build host
    into a live image (and others).
