Thanks.  I should have tried that before posting.  (It was one of
those cases of hitting <cr> and then wondering "just how hard would it
be to turn off selinux...")  Turning selinux off from either grub.conf
or the selinux conf file didn't change the failure one bit.  As you
suspected, it wasn't selinux related.

A bit of gdb-ing after figuring out the SRPM magic, showed a problem
with flock() failing.  Next step - figuring out why a linux client
can't flock a file on an openbsd server.
