Not AFAICT. But it's never to late to start writing a wiki. > I did a reasonably typical install from DVD-1 of Debian 9.1.0 . "reasonably typical".

You could then reconcile that with the contents of /etc/fstab and the /boot/grub/grub.cfg you think was used. (I am aware that you typically mangle the installation of grub.) ls -l /dev/disk/*uuid will give you a list of potential UUIDs that the system might be looking for. The probability is quite high that they are all unique in as few as the last five characters. > I know that many log files are under /var/log/ . > I used an operable system to examine the files on the failed > partition and could not find a useful readable file.

Yes, it would probably be an interesting name for the rest of us to know, but I realise that it would not be typical for you to reveal it. Cheers, David.
