[plug] cdrom

[BillK]

Hi,
	I am having problems dismounting the cdrom on my Mandrake system.

What happened was:
1) mounted cdrom (Mandrake supermount is disabled)
2) mounted remotely from another mandrake machine - its nfs exported.
3) Installed some packages from it
4) dismounted OK
5) refused to dismount from server (root) saying busy
6) umount -f also failed.

In frustration I manually ejected the disk to get it out.
This has happened whenever I have remotely mounted the cdrom.  The only
cure I have been able to find so far is reboot - is there a better way
of forcing a dismount?  As far as I can tell nothing is mounted, no
loopback involved.  Even logging out of all screens etc fails to restore
it.  I suspect its NFS, but how to reset it?
