Thanks for the information, but I notice that it was put into stable
*very* recently, so I hope it gets into 8.0-RELEASE.  I wasn't too
worried about it since the workaround was obvious once I identified
the problem.  I actually prefer to use Reiserfs, but it appears that
nobody is working on rw access for it.  Like the original poster, I am
a Debian user who is experimenting with it, but from VirtualBox for
now.  I will probably try setting up dual boot when 8.0 comes out.
