I think we get into the realms of Unix philosophy at this point.

What actually needs to be fixed is the ability to set permissions on
network ports and other 'root only' system facilities. Then rsyslog
could be started as a non-privileged user and still get the facilities
it requires.

This 'obtain what you require and then drop privileges' is a nasty workaround.

To be honest I prefer the Debian workaround where a root only process
grabs the relevant data and resurfaces it via a named pipe - with the
appropriate access permissions. Perhaps rsyslog should look at
adopting that approach for access to 'root-only' facilities. It
certainly prevents security holes.
