[arch-general] Licensing of Arch Wiki content

I notice it's all under GFDL 1.2. I'm wanting to use a Gentoo doc for the Arch Security stuff but it's under a CC-SA attribution license which is incompatible with GFDL. Would it be possible to allow Wiki content under a CC licenses? I can't see it being too controversial a choice, as in CC licenses are now widely accepted. Even the venerable RMS uses CC licenses for his personal stuff as does a lot of the FSF/GNU stuff. Ananda
