Hi, thank you for your comment, but I am weak in English. 
so I will read at later in detail, and I would like to ask the only point.

I make kernel built in ATA drivers, and make install kernel with
distrib/mac68k. In the result, I look disklabel in wd0, and change
fstype from HFS to 4.2BSD. but the later, sysinst terminated with
"Couldn't open /etc/disktab". Surely, it doesn't exist. I stopped there.
It's troublesome for me to write disktab, I want to only change fstype...
