-----------

The `svc/` conditions can be quite tricky to understand. They are

generated by the Finit `pidfile.so` plugin and are composed from the

daemon's path and the pidfile name (and path).

that can handle module loading better. The former supports loading

* `cgroup <NAME> cpuset:SPEC cpu:SPEC mem:SPEC`

Create a control group for resource limiting services using cgroups.
|
||||
Unlike `rlimit` this setting defines a common group to be selected for

any set of run/task/services using the `group` directive (below).

A cpuset for a cgroup can be the traditional list of CPU cores to

assign to the group, or a range that Finit will use to dynamically
|

allocate cores based on the amount available. The range values can be

either in absolute form or percent.

```shell
