    That's a subjective question.  I'd imagine it looks quite similar to some
    and starkly different to others.

    No shipped X at all, not enough to run X stuff in anyway.  You can,
    however, get X pkgs from pkgsrc.

    Nope. Too different for that.  You can image-create into a new BE, but
    that's certainly not an update.

    Yes. pkgrecv them.

    Not as a baked in feature, but there is post-install scripting available
    and you could easily make that happen without modifying kayak. (just zfs
    recv the extra data sets over the network after the rpool is recv'd).  I
    think you'll be pleasantly surprised by the simplicity and power of kayak.
