From Debian package 0.0.20080702-1
Updated in 0.0.20080702-12 (changed __default__ from s0 to s0-mcs_systemhigh)
0003-Make-default-and-root-mcs-seusers-unconfined.patch

Make root and __default__ map to unconfined_u

Make the default range for MCS __default__ users be s0-s0:c0.c1023,
this fixes a problem with restarting daemons after logging in as non-root
and running "su -".
