I think that I mentioned that I have scripts for setting up a ubuntu
computer depending on roles chosen for it, setting up user accounts

This approach was recently confirmed as the hard drive in the old 10"
laptop, finally died.

The amount of valuable data or setup lost, nothing.

Reinstalling it will be a breeze, though it will take time to redo
netinstall, it will not involve much work for me, just waiting for
stuff to get downloaded.

On the plus side, I will replace a 30 GB drive with a 160GB drive.
