Since I started maintaining the SELinux policies for Gentoo Hardened, the policy types we supported were primarily strict and targeted. About half a year ago, we also started supported mcs and offered the possibility for using mls as well (but didn't really support that one).

With the recent release of the newer userspace utilities, we found out that Gentoo Hardened is one of the few distributions that still really supports policy types without levels (MCS and MLS have support for levels, strict and targeted don't) as libsemanage had a failure when running simple activities on a system without level support. The fix is fairly trivial, but it does gave me the signal to start moving towards MCS.

So, now that the new userspace utilities are in the hardened-dev overlay (please test them ;-) I will now focus on the 2.20120215 policy release, getting that in good shape (forward-porting the patches that haven't made it to the refpolicy repository yet) and then see how we can transition users from strict or targeted to MCS (documentation, upgrade guide and software or packages when needed) so that we are up to par with the majority of other distributions.

I personally like the strict policy type as it is fairly simple to explain to users, but I'm sure I can deal with MCS and (in the future) MLS equally well ;-)
