# systemd

The `systemd` module of the mesh catalogue: installs the package `systemd`; claims the seat `node-service-manager`.

## Files it does not know

Each directory or archive this module declares says how it treats a file it did not write (ADR 0422, ADR 0416).

- `${dir:data}` (`/var/lib/mesh/<module>`): everything in it is the program's; the mesh moves nothing out (ADR 0422 §2).
- `${dir:state}`: the package's own directory, declared for one delivery with the package's owner and mode so the node-engine gives it back (issue 1873); the module keeps nothing there.
