>Description:
The page in question: http://www.freebsd.org/doc/en/articles/solid-state/kernel.html

The entry "options MFS" causes an error when attempting to build the kernel. The build error occurs after attempting "sudo make buildkernel KERNCONF=SENKBEIL" with SENKBEIL being a copy of the GENERIC kernel with the option "options MFS" appended.

The error reported is 'unknown option "MFS"'.
>How-To-Repeat:
Add "options MFS" to the kernel configuration and attempt to build the kernel.
>Fix:
Make a note on the documentation that this option is not valid for 9.1-RELEASE? Not sure when it became deprecated/removed.
