* Atomically replace the /bin/sh symlink; otherwise there is a time
window in which /bin/sh is missing. This can cause concurrently running programs to fail (e.g. Hydra jobs => http://hydra.nixos.org/build/2267831). You'd think the odds of this are very low, but they're not. svn path=/nixos/trunk/; revision=32901
