Many thanks for your email, David.

Apologies for any contradictory messages i have posted. My understanding of
the automatic mount of USB devices has been rapidly evolving.

I have now seen that people have had various problems with usbmount over
the years, so I can quite understand why it might not be in the  most
recent Debian distributions.

My plan is to update my distribution very soon, but first I need to do a
backup of the system to a USB portable hard drive (which uses NTFS).

I would like this backup to go as smoothly as possible.
