Hi!

I've just spent a day and a half trying to get one of our 4000's to
boot off a 3000 (as usual). Every time I got the same error:

	(blah, blah, blah, bytes loaded...)
	81270001 Boot error: can't get UID

-the code means 'operation attempted on unopened stream'

I thought this was due to the fact that I had changed some acl's
rather foolishly in our authorised area (which is hard linked to the os
on that node). I'd gone around making sure everything that needed
setuid'ing, etc was done. I replaced whole trees with links to other
nodes, all to no avail. I eventually tracked the error down to
emanating from netboot (by searching through the binary), but got no
further. I was so bemused by this stage I though it would be a good
idea to finally put 10.2 on the node. Then someone who had just added
a 4000 sr9.7.1 node to our network, which wasn't yet catalogued wanted
it to print via our nodes. I happened to catalogue it on the same node
I couldn't boot diskless off and HEY PRESTO! As if by magic, the
diskless 4000 started booting, and has been ok since.

Can anyone out there explain this? If I hadn't had to spend most of my
time fixing acls set by choosing 'closed' this wouldn't have confused
me and I wouldn't have wasted my time :-<)
