/etc/fstab on the thin-client.

Ah ha! cdpinger is crashing because lsof is not installed. After 
installing lsof, CD-ROMs are working. Why is the symlink created under 
/media? Is this yet another arbitrary LTSP 4.2 incompatibility? Can we 
get a link under $HOME/Drives/ as well?

After ejecting the CD, I am getting "VFS: busy inodes on changed media." 
on the client and /dev/cdrom is still mounted (after removing the disc 
from the caddie!). I tried ejecting again. It refuses to unmount 
cleanly. I suspect that I can use lsof to diagnose the problem but I 
don't know the magic options. I can mount another CD and it seems to 
work. In other words, the faulty unmounting does not seem to affect 
subsequent mount requests. Now the VFS message stopped appearing. 
Perhaps it is nothing to worry about?

Nothing happens when I inserting a floppy. If I mount the floppy by 
hand:

  mount -t vfat /dev/fd0 /var/run/drives/floppy0

I see udevmonitor messages "mount@/block/fd0" but /etc/fstab is not 
updated (on the client) and nothing appears on the server.

OK, that's another point for the LTSP 4.2 migration guide.

Yes, I have LTSP 4.2 running as well. LTSP 4.2 uses fuse and it works.

Yes.

Yes, I see ltspfsd running on the client in ps -Af listing.

It's running therefore it is installed.

That's just a HOWTO, not a troubleshooting guide.

Hrm, I made the changes suggested in 416673. I did not test whether the 
CD-ROM was not working without the changes. Do you want me to try it?
