Difference between this modification when mounting simplefs with wrong fs type:

Before:

    mount: /home/yoyi/simplefs/test: permission denied.

After:

    mount: /home/yoyi/simplefs/test: wrong fs type,
    bad option, bad superblock on /dev/loop17,
    missing codepage or helper program, or other error.
