[systemd-devel] Support for pre-restart check

Hi,

while looking at how to convert sysvinit scripts to service files in
Debian, I noticed that some scripts do an additional sanity check during
the restart action. That is, they run an extra command to validate the
configuration and only restart the service on success.

Systemd doesn't seem to provide such an option so far. Would you think
this is something one would like to see? If yes, what about the
following idea:

Add an ExecRestartPre option in the [Service] section. These commands
are executed when a restart is requested, before the service is stopped.
If they fail, the restart is aborted with an error.
