Description=MARS global trigger from /mars/userspace/systemd-trigger
Documentation=https://github.com/schoebel/mars/docu/mars-manual.pdf

## Prohibit parallelism with any daemon-reload
After=daemon-reload.service

## The global trigger calls "marsadm systemd-trigger-extern" _without_
## resource argument.
## The global variant will only generate any new templates, but will not
## activate/deactivate them (except when they are new).
## This is necessary for race avoidance with per-resource triggers.
## Only the per-resource triggers (see mars-@{res}-trigger.service)
## are allowed to actually start/stop any units dealing with resources.
