Subject: [PATCH] Make sure the mount units pulled by 'RequiresMountsFor=' are
|
|
|
aed857 |
loaded (if they exist)
|
|
|
aed857 |
|
|
|
aed857 |
We should make sure that mount units involved by 'RequiresMountsFor='
|
|
|
aed857 |
directives are really loaded if not required by any others units so
|
|
|
aed857 |
that Requires= dependencies on the mount units are applied and thus
|
|
|
aed857 |
the mount unit dependencies are started.
