"Ah, there's the rub" (From Hamlet, I believe).

As Ubuntu apparently uses the UUID instead of the device path, in the 
fstab, in the filesystem column, how do I get the UUID, to get a 
partition mounted?

I have now managed to get the particular (hdc8) partition mounted, and 
writable, and written to, in Debian, but I now do not know how to get 
the file mounted in Ubuntu.

If I try to get the UUID for the partition, by using the "vol_id -u" 
command, it returns "error opening device", I assume, because the device 
is not mounted.

So, as I cannot mount the device, without the UUID, how do I get the 
UUID, if the device is not mounted?

Thank you in anticipation.
