Diskless installs?

[Mouse <mouse%Rodents-Montreal.ORG@localhost>]

I'm trying to help a friend who wants to install 10.1 i386.  In aid of
this, I'm trying to set up to PXE-boot 10.1 diskless system.

I've got PXE booting working fine for 5.2.  So I started to set up
10.1.  But, looking at 10.1's INSTALL.more, I don't see anything at all
by way of diskless install instructions.  Am I missing something?  Or
is diskless installation now unsupported?  Surely not....
