Control: affects -1 live-boot
Dear initramfs-tools maintainers,
daily builds of Grml started failing today. I've debugged it a bit,
and it seems to boil down to this combination:
1) our builds run in a containerized environment, and thus have no
/sys or /proc. This is /good/ for building Live images, as leaking
anything from the build host would be wrong anyway.
2) live-boot hook.live does "set -e" right at the start:
https://sources.debian.org/src/live-boot/1%3A20250225/backend/initramfs-tools/live.hook/#L3
3) hook-functions _call_dracut_install reads from
/sys/module/firmware_class/parameters/path
without checking if the file exists (or otherwise allowing for set
-e), and this causes the entire process to abort.
Happens here:
https://sources.debian.org/src/initramfs-tools/0.146/hook-functions/?hl=106#L122
In add_firmware there's a similar code path, I assume that will also
be a problem:
https://sources.debian.org/src/initramfs-tools/0.146/hook-functions/?hl=106#L65
I understand that this combination might be somewhat surprising, but
it is very valuable for building live "CD" images. And so far it
worked really well.
Please consider short-circuiting the read from
/sys/module/firmware_class/parameters/path
somehow, and please for trixie.
Best,
Chris
