New Revision: 209210
URL: http://svn.freebsd.org/changeset/base/209210

Log:
  Allow population of /cfg and /data.  Begin the move to making all
  slice creation overrideable too, but there's a few problems doing that
  for the duplicated partitions (s1 and s2), so just comment that it
  needs work.
