Hi all,Some notes:* I would rather take my GNOME 3.4 snapshot and upgrade it to 3.6, rather than taking my 3.8 snapshot and downgrading to 3.6 (since the [Downgrading Packages][0] page on the Arch wiki says not to downgrade packages if possible).* I will certainly add gnome and gnome-extra to IgnoreGroup on all my VMs to freeze the versions as they are -- thanks! However I can't do this until I have a 3.6 VM.I guess it doesn't matter if I mess around with the downgrading though, because I can just take lots of snapshots to restore to :)I will play with a few methods (I think I need to keep searching the Arch wiki for ways to upgrade to a specific version rather than downgrade to a specific version, but failing that I'll downgrade from 3.8) and report back.
