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 2019-03-12 19:23:25 +00:00			`After=local-fs.target systemd-tmpfiles-setup.service`

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. 2019-12-18 08:14:57 +00:00			`ExecStart=journalctl --update-catalog`
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... 2015-02-02 20:34:32 +00:00			`TimeoutSec=90s`
