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