shutdown. (Portmap and statd are needed during shutdown to unmount NFS volumes but have open files in /var/run.) * In the shutdown job, don't kill PIDs belonging to Upstart jobs that are still running. If they don't stop on the "starting shutdown" event, then they're needed during shutdown (such as portmap and statd). * NFS test: test whether the shutdown quickly unmounts NFS volumes (i.e. whether portmap and statd are still running). svn path=/nixos/branches/boot-order/; revision=22204
