However it is not because a file has been modified that systemd should decide to reload by itself. multiple unit files need to work together to make a working environment, and systemd can't know when all changes are consistent and it is safe to reload. So systemd will want an explicit order from the user.

Hopefully there are not too many missing features I'm used to have in there...
