/nix bind mounted from a fs not rootfs. As niksnut found, if the sources of bind mounted directories are umounted before remounting them as "ro", a "mount -o remount,ro" on the bind targets will not leave the filesystem properly umounted, the same way as a "-o remount,ro" would do on a usual filesystem. So, the trick of always remounting as 'ro' before attempting an umount seems to fix the problem. svn path=/nixos/trunk/; revision=19008
