/sbin/mount.gfs2: can't find /proc/mounts entry for directory /

    The gfs2 mount helper was identifying devices by name rather than
    by number.  That works fine most of the time, but not in all
    cases, like when the root file system is gfs2.  This patch uses
    device ids to identify the devices, as it should be.
