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

["'Prusty, Badrikesh' via isar-users" <isar-users@googlegroups.com>]

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.

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.
