Change 41480 by rwatson at rwatson_tislabs on 2003/11/05 13:52:45

	Attempt to trim SEBSDisms from trustedbsd_mac without
	trimming from trustedbsd_sebsd.  This should leave the diffs
	between MAC and SEBSD branches being the differences necessary
	to add SEBSD, rather than a subset.  More commits to come.
