Nah, native filesystems on both systems, local disks.

Yes, it should.  I was thinking last night that perhaps the
always_purge option does not parse `svn status' correctly?  Note that
in the output:

  tfogal at octagon build svn status
  ?       Makefile.tvk
  X       Basics
  X       IO
  ?       .buildbot-sourcedata
  ?       Build/objects
  ?       Build/libTuvok.prl

  Performing status on external item at 'Basics'

  Performing status on external item at 'IO'
  ?       IO/expressions/Makefile.libexpr
  ?       IO/expressions/libtuvokexpr.prl
  ?       IO/expressions/Makefile.debug
  ?       IO/expressions/lexdbg

the external repositories have "X" next to them, instead of "?"s.
Purge should ignore the 'X's, I imagine.

.. but in thinking about it now, even if purge deleted the X'd
files/directories, the update should fix it.
