mount: wrong fs type

# mount -t nfs -o nolock 192.168.1.84:/home/jason/filesys /mnt/nfs
mount: wrong fs type, bad option, bad superblock on 192.168.1.84:/home/jason/filesys,
       missing codepage or helper program, or other error
       (for several filesystems (e.g. nfs, cifs) you might
       need a /sbin/mount.<type> helper program)
       In some cases useful info is found in syslog - try

       dmesg | tail  or so

# ls -l /bin/mount
lrwxrwxrwx    1 root     3355           19 Oct 21  2013 /bin/mount -> mount.util-linux-ng

# ls /bin/mount.util-linux-ng -l
-rwxr-xr-x    1 root     3355        56044 Oct 21  2013 /bin/mount.util-linux-ng

注意：mount.util-linux-ng不支持NFS

改动为：

#busybox mount -t nfs -o nolock 192.168.1.84:/home/jason/filesys /mnt/nfs
