True, so if Gilles' dad really wants to run dump, he most likely can.

The .snap directory in the root of a (mounted) file system to be dumped 
has owner root, group operator, mode 0770 - paraphrasing from dump(8) -
and then he'd need mount and write permissions on the dump destination.

Doesn't sound too risky if Gilles trusts him enough to run shutdown :)
