We run three MOSIX (not OpenMosix, though) clusters where all users'
home directories are on AFS and all logins are handled via AFS.

Our MOSIX clusters consist of a head node that the users log on to and
a number of diskless slave nodes that act merely as spare computing
resources for the head node.  The MOSIX traffic is always on a private
internal network with no visibility to/from the real world, so the
slave nodes have no idea of AFS.  Users start all jobs on the head node
and MOSIX takes care of distributing them across the nodes.  When the
jobs need to do I/O they migrate back to the head node.  (Yes, this is
a bottleneck.)

We haven't had any problems that I could pinpoint to interactions
between MOSIX and AFS.  What kind of failures have been reported?
