Sorry, I have not included that info originally. No, it shows /dev/root
there too:

    root@(none):/# cat /proc/mounts 
    rootfs / rootfs rw 0 0
    /dev/root / ext3 ro,relatime,barrier=0,data=writeback 0 0
    devtmpfs /dev devtmpfs rw,relatime,size=61564k,nr_inodes=15391,mode=755 0 0
    tmpfs /lib/init/rw tmpfs rw,nosuid,relatime,mode=755 0 0
    proc /proc proc rw,nosuid,nodev,noexec,relatime 0 0
    sysfs /sys sysfs rw,nosuid,nodev,noexec,relatime 0 0
