Where has BOOTMFS gone?

[Valentino D'Ostilio]

Hello,
    In FreeBSD 4.x I was able to use the BOOTMFS kernel configuration 
file to create a kernel with a root file system within it.  In 5.X this 
configuration has disappeared and I'm not quite sure how to replicate 
this in 5.x.  The procedure I am following is outlined at 
http://ezine.daemonnews.org/200211/monolithic-kernel.html in case anyone 
is interested.  Thanks for your time.
