units: reorder/split unit dependency blocks The block is reordered and split to have: 1. description + documentation 2. (optionally) conditions 3. all the dependencies I think it's easier to read the units this way. Also, the Conflicts+Before is seperated out to separate lines. The ordering dependency is "fake", because it could just as well be After=, we are adding it to force ordering wrt. shutdown.target, and it plays a different role than the other Before=, which are about a real ordering on boot. 2022-09-14 12:39:10 +01:00
units: restore ConditionNeesUpdate=/etc in ldconfig.service (#3311) In order to support stateless systems that support offline /usr updates properly, let's restore the ConditionNeesUpdate=/etc line that makes sure we are run when /usr is updated and this update needs to be propagated to the /etc/ld.so.conf file stored in /etc. This reverts part of #2859, which snuck this change in, but really shouldn't have. 2016-05-21 23:09:18 +02:00			`ConditionNeedsUpdate=\|/etc`

units: add ordering dependencies on initrd-switch-root.target For shutdown, we queue shutdown.target/start, so in every unit which should be stopped before shutdown, we need both Conflicts and an ordering dependency with shutdown.target (either Before= or After= would work, because stop jobs are always ordered before start jobs). For initrd transition, we queue initrd-switch-root.service/isolate. This automatically creates a /stop job for every running unit without IgnoreOnIsolate. But no ordering dependency is created, unless the unit has a (possibly transitive) ordering dependency on initrd-switch-root.service. Since most units must stop before the transition, we should add the ordering dependency. It is nicer to use Before=initrd-switch-root.target for this. initrd-switch-root.target is ordered before initrd-switch-root.service, so the effect it the same when both are in a transaction. Fixes #23745. To also cover the case where somebody is emergency mode in the initrd and queues initrd-switch-root.service/start (not isolate), also add Conflicts=initrd-switch-root.target, so various units are stopped properly. This extends 2525682565b372b9b83c848bfe89c025fed47a1d to cover all the other services that are touched. It could be consider "operator error", but it's easy to make and it's nicer if we can make this more foolproof. 2022-09-14 12:39:10 +01:00			`Conflicts=shutdown.target initrd-switch-root.target`
