[pacman-dev] [PATCH] Add support for multiple 'Architecture' values
From: Dan McGee <dan@archlinux.org> This allows architecture to be multivalued. On x86-64 machines, this could be something like: Architecture = x86-64-v3 x86-64 We use the first specified Architecture value in mirrorlist $arch variable replacement, as this is backwards-compatible and sane.
