Ooops, fixed patch.
john
# HG changeset patch
# User john.levon@xxxxxxx
# Date 1167403005 28800
# Node ID a18e42ef75a880637414d697102f534f8653b61a
# Parent 819689bd07959241a860c29c01bf7d8a259f00ff
Enable xend to pick up properties from SMF on Solaris. Also rename XendRoot
to the much clearer XendOptions.
