Alright, I have talked to a few people in IRC. This solution seems to work: * IUSE_IMPLICIT="prefix" in base/make.defaults (for EAPI-3 and greater) * prefix in base/use.mask (so no profiles will be able to use it unless specifically unmasked) * unmask USE=prefix and force it in prefix profiles - not in gentoo-x86 yet Patch located here if anyone cares to look: http://dev.gentoo.org/~darkside/tmp/USE-prefix.patch This is the combined logic of this thread, anything I overlooked? Thanks, Jeremy
