If you mount write protected removable media (FD, PD,..) 
without read-only option, and write something, 
and un-mount, then system panics. This is dangerous,
because I sometimes forget un-protecting these media.

Linux mount automatically adds read-only option, when 
mounting write protected media. This is safe...

Fix: 

How about adding read-only mount option automatically
like Linux mount.
How-To-Repeat: 1) mount write protected removable media.
2) write something this media.
3) un-mount this media.
