    I think that's more than just that.

    when you have a problem you want to be able to quickly have a netbootable
    kernel not spend time making initrd images.

    One could argue that you should have ready emergency disks ahead of time,
    but in my experience by time you need a boot disk something changes and
    they are not what you expect them be. for example I have there this box
    with 460+ days of uptime... the sources for the kernel I used to compile
    it are long gone, heck I even don't remember what ethernet card it has
    anymore (dmesg output is long gone, an I'm too lazy to open the box up,
    but for sure it is not a pci card.. )

    Another issue is development of new machines. when you port to a new
    machine, it come out handy be to able to simply netboot it.

    perhaps it would be a good idea to instead putting everything into
    initrd, to follow the patch netbsd took and simply make two stage
    boot loader. I think it might be more flexible than initrd is.

    I haven't looked at it for a while, but IIRC the first stage would
    do basic booting (bootp?) then load the proper kernel and pass
    ip options to it.
