Emergency Boot and Root Diskettes and 5.0.7 - SCO

    Not specific to 5.0.7 - We've had a number of systems (mostly Compaq,
    with the EFS installed) that would not allow us to fit the kernel onto
    floppy since around 5.0.4. We ended up paring the kernel down
    (removed SMP, EFS, etc. - Anything non-critical for a restore kernel)
    and _then_ creating our boot/root set. Of course, you have to go
    through the hassle of re-installing those pieces.

    Side note: Most of our customers have, unfortunately, not seen the
    benefit in using one of the Supertars. Anyone know if there will be
    the ability to create bootable CDs using mkdev fd? Or is there
    currently a way to do this that I am not aware of?
     

    My guess(tm) is that this would work fine - The contents of the tape
    *should* overlay /stand as well as any additional filesystems.
    Unitrends support would be the best to field this question.

    Huh? What's on the tape is what's on the tape. When you write from the
    tape to the hard drive, you aren't writing from the floppy to the hard
    drive.

    Why wait on Unitrends, though, when Lone-Tar and BackupEDGE do now work
    on 5.0.7?

    Have you noticed that on 5.0.7 you can format 1.68MB floppies when running
    mkdev fd? Can you not fit either kernel on these slightly larger floppies?

    I noticed that on my first 5.0.7 system when even RecoverEDGE
    couldn't manage to fit the kernel onto one 1.44 MB floppy (on a Compaq
    system, which as someone else noted can be a problem - the Compaq
    EFS includes a whole bunch of stuff, some of which gets linked
    into the kernel).

    Telling RecoverEDGE to format the floppies as 1.68 MB diskettes
    fixed the problem; the server now has emergency floppies which are
    known to work (having learned long ago never to trust floppies,
    I made sure they worked).

    It's worth a try with mkdev fd, too, though I don't know if it
    does as good a job of shrinking kernels as RecoverEDGE does, and
    of course BackupEDGE/RecoverEDGE (or the other supertar products)
    offer so much more.
