md(4) rootfs mounted read only instead of rw on 6.1

[ovidiu]

Hello guys

I've wrote a script that create an cd bootable iso of a small base 
filesystem, to boot from CD.
In FreeBSD 5.4 it worked ok, but I've moved to 6.1 release and here 
after boot it mounts the root partition read only.

I don't understand why since: i've created with mdconfig -o noreadonly, 
I have in fstab mounted md as rw, in rc.conf i have a variable to mount 
root file sistem read write...

any ideea why is that happening in FreeBSD 6.1-RELEASE ? (the problem 
was also in 6.1-RC2)

best regards
ovidiu
