[PATCH v3 0/1] image-postproc: ignore systemd preset failures

[PATCH v3 0/1] image-postproc: ignore systemd preset failures

['Badrikesh Prusty' via isar-users]

changes in v3:
* Do not disable pre-population of enabled systemd services during build,
  as this is the correct default behavior. Downstream layers can disable
  it if needed.
* Ignore failures from systemd preset only.

changes in v2:
* Disable populate-systemd-preset at build time by default due to service
  failures observed on some systems.

[PATCH v3 1/1] image-postproc: ignore systemd preset failures

['Badrikesh Prusty' via isar-users]

Add '|| true' to systemd preset invocation during image postprocessing
to tolerate failures caused by already-masked units.

This is still too coarse. Currently the presetting fails on bullseye
targets with the following error "Failed to preset: Invalid argument.".

While I did not check the root-cause, I'm pretty sure this is a
different error which would be hidden by || true.

Re: [PATCH v3 1/1] image-postproc: ignore systemd preset failures

['Prusty, Badrikesh' via isar-users]

Hi,

I guess the error of invalid argument is due to invalid preset configs
in /usr/lib/systemd/system-preset/ or the preset files missing in
system-preset/ directory. With my initial check the `preset-all` and
`preset-mode` flags are available since systemd v215.

For masked service failures, I tested this on my systems locally with a
newer version of systemd as well. The command also fails with exit code
1 when running the preset on Debian Trixie and Forky. I’m not sure how
the builds for Trixie continues despite these failures.

Is this series aiming at these new warnings of Isar?

DEBUG: Executing shell function image_postprocess_disable_systemd_firstboot

your invocation environment to mount /proc/ and /sys/ properly. Proceeding anyway.

Hmm, no. This seems to be another to-do for Felix' rootless patches. I
was running them, and this warning is gone when going back to vanilla Isar.

Good catch. We need /proc and /sys mounted, which we currently not do
in this task.
