 Does anyone else have a multi-user compute cluster of Opterons?  I manage
one at work, and I've been thinking about how to let users chroot into the
64bit system.  Has anyone already figured out what to put in sudo.conf to
let users  chroot /amd64 su - $USER?  /amd64 is a partition with a pure64
install, and /home is bind-mounted inside it.  I haven't even considered
booting a 64bit users space, but I want to be able to run in 64bit mode to
gain a bit of performance for our bioinformatics number crunching.  I
installed a biarch 2.4 kernel, since something didn't work right when I
tried a 2.6.  (don't remember what, though.)  I'm hoping to get openMosix
ported to AMD64 soon, and its 2.6 port is still pre-alpha, so we'll probably
be running 2.4 for a while.

 Or would it make more sense to run sshd inside the chroot, listening on a
different port?
