In  the tftpboot directory there should be a symlink to ../tftpboot. I
think this  fixes some weird problems with netbooting different hardware
from different manufacturs.

I think it is a side effect of using M$ products.

It is very  wrong. However linux, being what it is, doesn't even hint
that multiple partitions may be a good thing. After all, after using M$
OS's where having more than one partition causes more problems than it's
worth, why would someone comming to the not so dark side want all the
trouble of multiple partitions. 

No comments about people only haveing root accounts on the box and
always working as root.

I was also curious about this.

There was  some other reasons for /space. I thought the idea was  to have
mussel a multi OS box and the /space was there for fast compiles of
different parts of OS's.

While this is a good idea I can see that it will be doomed to failure. I
think that packages may have something to do with it.
