Dear devs, guys: I've been struggling for the past three days trying to find what was breaking makepkg [0] script and preventing Firefox to launch. Thanks I do weekly backups of my system I found after trial & error -updating one package at a time- the responsable is the core/filesystem package. Is anyone else suffering this? I already tried to look for info in www.archlinux.org/packages but it's not listed there. Should I open a new ticket at the bugtracker? Thanks for any advice. 0. Here are some logs: makepkg output after installing new filesystem 2010.12-1: http://aur.pastebin.com/VzRUu6yN /etc/makepkg.conf (untouched): http://aur.pastebin.com/RnqjbYaX last pacman's log with filesystem 2010.12-1 package installed: http://aur.pastebin.com/rZtXgifP
