Documentation=man:systemd-journald.service(8) man:journald.conf(5)
DefaultDependencies=no
Conflicts=shutdown.target
units: update catalog after systemd-tmpfiles runs `systemd-journal-catalog-update.service` writes to `/var`. However, it's not explicitly ordered wrt `systemd-tmpfiles-setup.service`, which means that it may run before or after. This is an issue for Fedora CoreOS, which uses Ignition. We want to be able to prepare `/var` on first boot from the initrd, where the SELinux policy is not loaded yet. This means that the hierarchy under `/var` is not correctly labeled. We add a `Z /var - - -` tmpfiles entry so that it gets relabeled once `/var` gets mounted post-switchroot. So any service that tries to access `/var` before `systemd-tmpfiles` relabels it is likely to hit `EACCES`. Fix this by simply ordering `systemd-journal-catalog-update.service` after `systemd-tmpfiles-setup.service`. This is also clearer since the tmpfiles entries are the canonical source of how `/var` should be populated. For more context on this, see: https://github.com/coreos/ignition/issues/635#issuecomment-446620297

units: fix condition for systemd-journal-catalog-update.service (#4990) The service is supposed to regenerate the catalog index whenever /usr is updated, but /var is not. Hence the ConditionNeedsUpdate= line should actually reference /var, as that's where the index file is located.

Type=oneshot
RemainAfterExit=yes
units: drop full paths for utilities in $PATH This makes things a bit simpler and the build a bit faster, because we don't have to rewrite files to do the trivial substitution. @rootbindir@ is always in our internal $PATH that we use for non-absolute paths, so there should be no functional change.

units: so far we defaulted to 90s as default timeout for most things, let's do so for our oneshot services too Fewer surprises, and stuff...
