I've never done it myself, but I can't see any reason why not. Hardened is a strict subset of non-hardened (in terms of packages and versions) so it should just be a smooth, albeit long, upgrade. There may well be USE flags involved that introduce incompatibilities that can't be resolved, I wouldn't know about that. I would also suggest you find a decent howto written by someone who knows the process. You definitely want to get your USE, CFLAGS and CXXFLAGS right the first time. Otherwise you'll end up recompiling lots of stuff over and over, each time with new settings you forgot about the previous time :-) -- alan dot mckinnon at gmail dot com > > Also, I've got this with my server: > > # eselect profile list > Available profile symlink targets: > [1] hardened/x86/2.6 * > [2] selinux/2007.0/x86 > [3] selinux/2007.0/x86/hardened > [4] default/linux/x86/2008.0 > [5] default/linux/x86/2008.0/desktop > [6] default/linux/x86/2008.0/developer > [7] default/linux/x86/2008.0/server > [8] hardened/linux/x86 > > Is there a difference between 1 and 8?
