Thanks for testing, and sympathies for the hardware trouble!

Can you suggest a better way to do this? In other words, when and in 
what circumstances would you want to see them again?

This is bad. I can modify it to check if a filesystem has been mounted 
at /mnt, and maybe if the fstab file exists and restart the disk editor 
menu if they have not.

That's a clear bug. It should probably only validate the setup if 'Save' 
is selected. The issue of whether it should allow you to save without 
defining a / partition when invoked from a shell is a more complicated 
one, and one I'll have to think about (suggestions welcome).

Yes, this should be prettified. It's running a few things (passwd, 
adduser) in a chroot, and I figured getting things working there was 
more important than making them pretty for now.
