## 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.
