1. test-fstab-generator: fix inverted /mnt symlink guard
The test-18-options.fstab.input scenario was guarded by a check
that was always true on a normal system, so it was silently
skipped and its fixtures had drifted out of sync with actual
generator output. This commit fixes the guard and repairs the
stale fixtures it exposed.
2. fstab-generator: support for x-systemd.onfailure
Add support for the x-systemd.onfailure= fstab option in
systemd-fstab-generator. This allows configuring OnFailure=
dependencies for generated mount units directly through /etc/fstab.
For example:
/dev/sda1 /data ext4 defaults,x-systemd.onfailure=emergency.target 0 2
results in the generated mount unit containing:
[Unit]
OnFailure=emergency.target
This makes it possible to attach recovery targets or services to
mount failures directly from fstab configuration.
Add documentation and generator tests.
