This is answered below (systemd is not running), but let me add one more reason why inotify wouldn't work: you cannot blindly reload units, because sometimes a set of units have dependencies between them, so you need to first install the full set, and then reload. > > Well, the point is that systemd isn't running or even installed when the > > daemons are installed.

Only the package scriptlets know whether some service is installed or upgraded and have enough information to properly support presets and restarts. > > I know this thread has gone in a completely different direction, but the > > original message was about modifying or removing the dependencies.

You seem to be missing normal containers: in those there is not kernel but systemd is and pretty much all services are running.
