I've read that FAQ as well as greg's book, Lucas's book, unix power tools, the man pages, handbook, etc. I will reread them again. >=20 > I can't say much about your main question; I've never heard of doing > it.

I've never heard of doing it like that too but it does work. I'm going to be working on this server today and I'll post some of the details of fdisk, bsdlabel, etc. to see if I can help clarify things. Thanks
