Ok will try this.

I'm afraid I've removed the custom kernel so I can't tell you. I assumed
that the reason was that I'd compiled and installed the kernel with
selinux as permissive. In any case, under my current setup with the
fedora default kernel:
[matt@localhost matt]$ getfilecon /etc/hotplug
/etc/hotplug system_u:object_r:hotplug_etc_t
To be honest my system is a bit strange at the moment, and I've put
selinux back in permissive mode, as I keep finding strange things that I
can't do with it in enforcing mode with no error messages (e.g.
Openoffice.org doesn't open and I can't do a "glxgears" - weird huh?!)
So it's probably that I've done something wrong. The installation of
fedora was of test 2 and I've been updating it until Core 2. So maybe a
clean install would be a good idea.
Thanks very much for all your help.
