    This may be getting a bit Off Topic, but I always find it annoying when
    archive thread peter out without any conclusion...

    I may have a chance to test this again, sometime, but the machine is
    installed remotely now and I don't know if they have a USB keyboard or
    not :-( If you made ukdb1 the console from the command line, then this
    would have gone away when the machine was rebooted.

    Why would you want to do this? 2 reasons I can think of:

        1) There actually are sometimes staff at the remote location, and
    having a keyboard next to the machine makes it easier to use the console
    at the same time as doing hardware things like inserting CDs. (Note
    that you can use a local keyboard if you are fiddling with the BIOS,
    since it's just FreeBSD which forces one keyboard). The same issue
    affects PS/2 keyboards as well as USB ones, btw.

        2) The DRAC keyboard through the Java app is a bit funny. Below is
    a quick message I wrote (not to this list) summarising my difficulties.
    The lack of a \ is a pain as there is rarely one on-screen to
    cut-and-paste. # less difficult since it's usually in some file which
    has other comments in it already.

    Neither of those *require* you to use a local keyboard, though.
