What exactly is the use case here?


 We'd like to isolate the process, and specify non-default IO and CPU
weights.
Something very similar to this:
https://github.com/scylladb/scylla/blob/master/dist/common/systemd/scylla-server.slice
,
which is explained in more detail here:

`

Is this a package shipped in Debian so we could have a look?

Nope, it's a private package, unfortunately.

Typically, services are run in the system.slice.
