 - [_Services_](http://www.freedesktop.org/software/systemd/man/systemd.service.html) encapsulate a number of processes that are started and stopped by systemd based on configuration. Services are named in the style of `quux.service`.
 - [_Scopes_](http://www.freedesktop.org/software/systemd/man/systemd.scope.html) encapsulate a number of processes that are started and stopped by arbitrary processes via fork(), and then registered at runtime with PID1. Scopes are named in the style of `wuff.scope`.
-- [_Slices_](http://www.freedesktop.org/software/systemd/man/systemd.slice.html) may be used to group a number of services and scopes together in a hierarchial tree. Slices do not contain processes themselves, but the services and slices contained in them do. Slices are named in the style of `foobar-waldo.slice`, where the path to the location of the slice in the tree is encoded in the name with "-" as separator for the path components (`foobar-waldo.slice` is hence a subslice of `foobar.slice`). There's one special slices defined, `-.slice`, which is the root slice of all slices (`foobar.slice` is hence subslice of `-.slice`). This is similar how in regular file paths, "/" denotes the root directory.

 Service, scope and slice units directly map to objects in the cgroup tree. When these units are activated they each map to directly (modulo some character escaping) to cgroup paths built from the unit names. For example, a service `quux.service` in a slice `foobar-waldo.slice` is found in the cgroup `foobar.slice/foobar-waldo.slice/quux.service/`.
