relicense to LGPLv2.1 (with exceptions) We finally got the OK from all contributors with non-trivial commits to relicense systemd from GPL2+ to LGPL2.1+. Some udev bits continue to be GPL2+ for now, but we are looking into relicensing them too, to allow free copy/paste of all code within systemd. The bits that used to be MIT continue to be MIT. The big benefit of the relicensing is that closed source code may now link against libsystemd-login.so and friends. 2012-04-12 02:20:58 +04:00			`# under the terms of the GNU Lesser General Public License as published by`

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 14:39:10 +03:00

units: add time-set.target time-sync.target is supposed to indicate system clock is synchronized with a remote clock, but as used through 241 it only provided a system clock that was updated based on a locally-maintained timestamp. Systems that are powered off for extended periods would not come up with accurate time. Retain the existing behavior using a new time-set.target leaving time-sync.target for cases where accuracy is required. Closes #8861 2018-04-30 15:05:29 +03:00			`After=local-fs.target time-set.target`
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 14:39:10 +03:00			`Conflicts=shutdown.target initrd-switch-root.target`

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 11:14:57 +03:00			`ExecStart=systemd-tmpfiles --clean`
units: use symbolic exit code names (nspawn uses 133 which doesn't have a name. That's reasonable, because there's less chance of conflict with a return value from the payload.) 2019-07-28 16:00:08 +03:00			`SuccessExitStatus=DATAERR`
