What is the best way to handle mount and export of CD-ROMs? The problem
I have is that the device must be mounted before it can be exported.

In my /etc/fstab I have:

/dev/sr0 /cdrom hsfs ro,noauto 0 0

The noauto prevents the cdrom from being mounted with a mount -a
on boot-up.

Then in /etc/exports I have:

/ -access=trusted
/usr/export -access=trusted
/cdrom -access=trusted,ro

So that the CD-ROM can be remote-mounted. When the machine boots I get:

exportfs: /cdrom: parent-directory (/)

Because /dev/sr0 is not mounted, exportfs thinks I want to export a
subdirectory of an already-exported directory.

If I delete / from the export list then export stops complaining --
but I haven't done what I want. I have exported the /cdrom directory
in the root partition.

What I am trying to avoid having to do is export /cdrom whenever I
mount a CD-ROM disk.

Any help would be appreciated.
