Let's stress one thing: delegation is available on scope and service units
only. It's expressly not available on slice units. Why? Because slice units are
our *inner* nodes of the cgroup trees and we freely attach service and scopes
-to them. If we'd allow delegation on slice units then this would mean that that
+to them. If we'd allow delegation on slice units then this would mean that
both systemd and your own manager would create/delete cgroups below the slice
unit and that conflicts with the single-writer rule.
Note one particular asymmetry here though: systemd will try to take possession
of the root cgroup you pass to it *in* *full*, i.e. it will not only
-create/remove child cgroups below it it will also attempt to manage the
+create/remove child cgroups below it, it will also attempt to manage the
attributes of it. OTOH as mentioned above, when delegating a cgroup tree to
somebody else it only passes the rights to create/remove sub-cgroups, but will
insist on managing the delegated cgroup tree's top-level attributes. Or in
