Indeed - I surely didn't expect that to be possible ...

Before, if you mounted a packagefs, it showed in Tracker as 'Package FS'
(i.e. always the same volume name for all mounted packagefs'), while in the
shell it showed as the mountpoint's original name. I'd like to replicate the
mountpoint's name as volume name, that's all.
Since the packagefs mountpoints would be part of PATH, I'd find it a bit
weird if those paths would be named differently in Tracker.
Actually, I'm going to have the same problem in bindfs that I planned to
implement tomorrow. Talking about that: do we have any documentation on
filesystem layers (overlays)? How are they mounted in general and can they be
mounted to a specific folder, too, or do they always overlay a complete other
filesystem?
cheers,
Oliver
