Subject: [PATCH] core: add a "Requires=" dependency between units and the
|
|
|
9ab0c5 |
slices they are located in
|
|
|
9ab0c5 |
|
|
|
9ab0c5 |
We place the processes we fork off in the cgroup anyway, and we probably
|
|
|
9ab0c5 |
shouldn't be able to get that far if we couldn't set up the slice due to
|
|
|
9ab0c5 |
resource problems or unmet conditions. Hence upgrade the dependency
|
|
|
9ab0c5 |
between units and the slices they are located in from Wants= to
|
|
|
9ab0c5 |
Requires=.
|
