No offense, but you're a bit late to be trying to shoot this down only now. Perhaps you recall Tom's post (and ensuing discussion) from a few months ago: http://www.mail-archive.com/[email protected]/msg19028.html With a followup: http://mailman.archlinux.org/pipermail/arch-dev-public/2012-March/022756.html Maybe the wiki page that detailed the plan: https://wiki.archlinux.org/index.php/DeveloperWiki:UsrMove Or when we started on this with todolist 143: https://www.archlinux.org/todo/143/ And did more of this with todolist 148: https://www.archlinux.org/todo/148/ What's the point of doing 95% of this and then polishing it off with some silly hack? /lib64 is already going away and turning into a symlink with the glibc-2.16 package in [staging]. d P.S. i686 rebuilds are done -- I've moved this all to brynhild to avoid the bandwidth restrictions on gerolde: http://pkgbuild.com/~dreisner/linux-usrmove/
