I have quite a few X kernels, and they work great. I start the display server
with the -query option and it contacts xdm without any other administration.
To do this however, I have to add the xdm server to the /etc/X0.hosts file
in the filesystem that the Xkernel sees - because I use an MIT X11R4 server
with access controls *enabled*.

MIT X11R4 xhost behaves differently when I do this. It's as though the 
xdm server is the local host!! In other words, running xhost on the xdm
server with -display set to the Xkernel machine works, but xhost on any
machine other than the xdm server gives the usual message that xhost only
works on the local machine.

Why does the display server on the Xkernel allow itself to be xhost'ed 
remotely from the xdm server?
