[mrtg-developers] [RFE] [PATCH] NoDetach configuration option

[Georgi Georgiev]

I am running mrtg under daemontools. They do a god job at restarting the child
process (mrtg) when necessary, but mrtg has to run in the foreground for that
purpose.

I would like to request the addition of another configuration option, that
would prevent the mrtg daemon process from detaching from the console.

The modifications I made to my local copy of mrtg are trivial:
