    The 6.2 version is obliging enough to do the same; and "at -f" will cause
    a segv (no core) as a regular user, and a coredump as root.
    
    
    About the 6.4 patch (number 3184) - swmgr complains about its current
    version being too old to handle the patch set; i haven't tried using inst,
    but i expect the same problem. has anyone else managed to circumvent this
    issue, and if so, how?
    
    thanks,
    Klaus
