Sure @bryanlunduke will agree, but I just made a total school boy error and f*cked my /usr/bin up. Luckily, I’m running openSUSE on this particular host and decided to chose the btrfs install option - which openSUSE makes so easy.
Long and the short is restoring /usr/bin was a piece of cake, because of btrfs’s snapshotting and I’m totally in their debt.
