As said, the root filesystem is read-only and the command "mount -uw /"
should be in disabled when securelevel==3, in my ideal kernel.

Actually the command "mount -uw /" will succeded when the securelevel==3,
but supposing should be not so difficult to change the FreeBSD kernel,
this (securelevel+readonly filesystem) could address the weakness of
securelevel+non-read-only filesystem.
