To me, this is related to the hw access discussion that happened not too long
ago on this list ('[RFC] Improving hardware access for snaps' -- the first step
to unblock people is actively being worked on and should hit a snappy image near
you soon). The difference of course is that mediatomb shouldn't have raw access
to a device in /dev, but rather access to files under the external drive's mount
point (eg /media). I think the straw man is a good start and has similarities to
what we've been thinking about for the next steps in hw access. I'll give this
some thought then bring it up for discussion here.
