Well, the handbook is a bit vague. I managed to boot via nfs after 
tweaking var and tmp in init.d. I told them that I have a ro /.
Then they created a /dev/md* (ramdisk, right?)
Ok, with this hack I was able boot, but I couldn't add a user nor was I 
able to create a master.passwd.

Ah, Ben the man. Ok, where would such a sequence go? 
arch/powerpc/macppc? ? cpu_setup ?

Second attempt. I reformatted the fw drive with 2 partitions swap and /
Worked after the 17th try :)

Ouch.

Ok.

Now I have to go learning fbsd.

For example I tried to build a kernel. Seems very unstable, I often got 
a sig 11 and retrying solved it until the next error.
Also, a buildworld was non predictable in behavior.

Thanks so far.

I will continue to try.
