12 Snapshot units are not configured via unit configuration files.
13 Nonetheless they are named similar to filenames. A unit name whose name
14 ends in .snapshot refers to a dynamic snapshot of the systemd runtime
15 state.

17 Snapshots are not configured on disk but created dynamically via
18 systemctl snapshot (see systemctl(8) for details) or an equivalent
19 command. When created, they will automatically get dependencies on the
20 currently activated units. They act as saved runtime state of the
21 systemd manager. Later on, the user may choose to return to the saved
22 state via systemctl isolate. They are useful to roll back to a defined
23 state after temporarily starting/stopping services or similar.
