Subject: [PATCH] rpm triggers: do nothing if systemd is not running (#5065)
|
|
|
03e93e2 |
|
|
|
03e93e2 |
If we are running in a chroot/container/..., we would print a useless warning about
|
|
|
03e93e2 |
not being able to communicate with systemd. Trying to do daemon-reload is pointless
|
|
|
03e93e2 |
in those cases, so let's just skip all actions in that case.
|
|
|
03e93e2 |
|
|
|
03e93e2 |
The check uses /run/system/system, as recommended by sd_booted(3).
