Comment:

 After having briefly investigated, it's clear that there are two
 fundamental issues at stake here. First, the Journal is being prevented
 from talking to Hal over the System Bus because the system bus has a
 default-deny policy and because no exception is made for Hal. Making an
 exception is easy; figuring out exactly the right exception to make is
 somewhat more challenging.

 Secondly, the journal (in joyride-235, which is what I am testing on) is
 supplying mount options to Hal (in volumesmanager.py) which are now
 incorrect - or at least, suboptimal. We want something closer to uid=500
 and maybe umask=000 than the current choices of uid=os.getuid() and
 umask=077.

 At any rate, the first piece of this - fixing mounting - seems to be
 fairly easy to do. Further testing will be required to make sure that the
 complete USB/SD usage pattern checks out.

 In particular, I managed to produce a Journal crash while trying to access
 a mounted file that I am currently investigating.
