[Fedora-xen] Cannot create files or dirs even as root on FC6 xen system

[Tan Chee Sin]

Hi Craig,

Thanks for the info.
Yes, autofs is indeed configured to dynamically mount the CDROM on 
/misc/cdrom. This is fresh install on a new system but it still have 
this style of config. Hmm...

I have commented out the culprit line and restarted autofs. I'm able to 
write to /misc now. =)
