With migration from 5.17.1 to 5.20.0 the "$HOST" variable has changed

[Marcus Mülbüsch]

Hello,

   I've upgraded from monit-5.17.1 to monit 5.20.0, but now the config 
line:

> check system $HOST

   is expanded only to "hostname -s", instead of "hostname -f" as 
before. This can be seen by the logfile on the server "mmonit":

> Nov 23 17:13:45 mmonit monit[7402]: 'mmonit.as-infodienste.de' Monit 5.17.1 
> stopped
> Nov 23 17:13:52 mmonit monit[31741]: /usr/local/monit.d/mmonit.monit:8: Service 
> name conflict, mmonit already defined '/run/mmonit/mmonit.pid'
> Nov 23 17:13:52 mmonit /etc/init.d/monit[31740]: start-stop-daemon: failed to 
> start `/usr/bin/monit'
> Nov 23 17:13:52 mmonit /etc/init.d/monit[31724]: ERROR: monit failed to start
> Nov 23 17:22:47 mmonit monit[3567]: Starting Monit 5.20.0 daemon with http 
> interface at [*]:10443
> Nov 23 17:22:47 mmonit monit[3567]: Monit start delay set to 15s
> Nov 23 17:23:02 mmonit monit[3570]: 'mmonit' Monit 5.20.0 started

   In this case it was especially bad, because I have defined a service 
"mmonit" that now conflicts with the hostname "mmonit".

   This also influences everything else: The mmonit Dashboard, the 
monit mails...

   How can I get the old behaviour back?

   Best regards,
