And if you're thinking of reinstalling a la pacman -S $(comm -3 <(pacman -Qq) <(pacman -Qqm)) then remember to put it in a list first, remove them (-Rscn) and then (re)install (-S). This is because some, if not many packages, contain post-remove/install commands that may affect the outcome. -- GPG/PGP ID: B42DDCAD
