Hmm, I wasn't expecting this sort of thing.  I guess we need to
monitor /etc as well to get events when the file gets added back or
renamed to /etc/hostname.  Any chance you could do a patch for that?
There's some directory monitoring code in
system-settings/plugins/ifcfg-rh/plugin.c that could be adapted for this
(the code in ifcfg-rh monitors /etc/sysconfig/network).
