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 2019-03-13 03:23:25 +08:00			`After=local-fs.target systemd-tmpfiles-setup.service`

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. 2016-12-29 17:38:52 +08:00			`ConditionNeedsUpdate=/var`

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... 2015-02-03 04:34:32 +08:00			`TimeoutSec=90s`
