The point is that when run as root, nagios really shouldn't dump core,
and especially not if it has read anything in /etc, since the coredump
can then contain snippets of files best kept for the eyes of root only.

You don't have to start nagios as root. You can do

	su - nagios -c "nagios -f nagios.cfg"

in your startup script.

In that case, make it a config variable in nagios.cfg. Something along
the lines of "runtime_directory" or something should work ok, and make
nagios bail if it can't change to that directory when daemonizing. It
doesn't change directory at all unless it goes into daemon mode.
