As you noted in your mail - it is possible to have a 32bit OSCAR
server
downloading and installing a 64bit OSCAR node. We do it and it
works.
And we do it exactly as you described using
systemimager.

Alex

Re: [Oscar-users] add new nodes
What you would probably have to do is
install the 64 bit OS on the nodes
by hand, pull a golden image off that node
with the systemimager tools
(not through oscar at this point) and then use
oscar to push that image
to the other nodes.
The kicker of this is
that you would still have to set up the first node
by hand (including all the
Oscar packages!) so just for fun you might
try your original clone/upgrade
idea on that node before pulling the
golden image back with
systemimager. I will be a bit supprised if the
upgrade from x86 to
x86_64 goes well, but stranger things have happened.
As a disclaimer, I
have never actually done this myself, I just know it
is possible with the
tools included with Oscar. From my understanding,
this is the way most
people use systemimager outside the oscar
community.
