Description=MARS TESTING dummy process running on /mnt/test/@{res}
|
|
Documentation=https://github.com/schoebel/mars/docu/mars-user-manual.pdf
|
|
|
|
## Markers for the template processor
|
|
# TESTING_START
|
|
|
|
## Prohibit parallelism with any daemon-reload
|
|
After=daemon-reload.service
|
|
|
|
## HINT: in addition to the combination of BindsTo= with After= as
|
|
## documented in "man systemd.unit" to get an _ordering_ dependency for
|
|
## startup, it looks like we also need PartOf= to get _another_ ordering
|
|
## dependency for _stopping_ in the right order.
|
|
## The docs were not particularly clear about this, I found this by testing.
|
|
|
|
## Comment / uncomment the following, depending on test behaviour:
|
|
|
|
## This version uses an intermediate "delay" service for testing.
|
|
## Notice: the pathname part of the delay service is generated by
|
|
## pattern matching from ^{mnt} . Look at the generated units.
|
|
## This setup also tests transitive systemd dependencies, where
|
|
## BindsTo+After+PartOf is crucial for starting and stopping any
|
|
## intermediate units in the right order.
|
|
#BindsTo=mnt-test-@escvar{res}-delay.service
|
|
#After=mnt-test-@escvar{res}-delay.service
|
|
#PartOf=mnt-test-@escvar{res}-delay.service
|
|
|
|
## Direct version without delay. Use in place of the delay service.
