Currently the "-s" option is ignored by the text-based mount interface. To
notify the kernel that sloppy mount option parsing is needed, add "sloppy"
to the string of mount options passed to the kernel.
The 2.6.23 - 2.6.26 kernels will fail the mount if "sloppy" is present, as
they won't recognize it. To prevent them from ever seeing this option,
have the mount command check the kernel version before appending the option.
