I'm only half convinced.  The trouble is that incremental archives created
with the --one-file-system option record mount points as if they are empty
directories, causing restore to delete files that couldn't possibly be in the
backup.

Suggestion: maybe gnu_restore() should take account of the --one-file-system
option to avoid deleting files in mounted filesystems?
