Question

Snow Leopard Netboot NBI for Casper Imaging

I have been trying to create a new .nbi boot image for Casper 7.1 for
imaging.
Using the Resource Kit, I have been unsuccessful using Snow Leopard as
the base OS.
What I have tried, was to create a Netboot image using System Image
utility, and have my OS auto login as root, and launch Casper Imaging.

When I do this, I get some sort of a dyld error complaining that the
cache was built on a different system, and then Casper imaging quits
and restarts in an infinite loop!

What would be the best practice for getting this new netboot image
accomplished?

Thanks!

    Hi-

    I've also been experimenting with this. I made a netboot image with system image utility off of a partition that had the Casper Imaging app in it. I made sure to select the image as "diskless" so that it can unmount and apply the image to it successfully. This seems to have worked, but I'm running into other issues (that I'm not sure are related to this method or not). Maybe that'll get you farther.

    This is actually the way we currently build our Casper boot images.

    So far, so good on 10.4 & 10.5. Regards,

    So far my 10.6.1 Netboot image has been working, although it's only been
    a week that I've been on it so "knock-on-wood"!

    I built up the image as a slim install, setting up Casper Imaging.app to
    auto launch at boot. (Be sure to set the system to auto-login as "root".

    Once that was all set up, I used the "System Image Utility" from the
    10.6.x server admin tools from Apple. (Be sure the server admin tools
    are the same version as the OS the Netboot image is created off of.)
    10.6.1 OS image created by Server Admin tools 10.6.1, etc.

    That's pretty much it in a nutshell..

    Hope that helps,

    Hi all,

    I have a working 10.6.1 nbi on my 10.5.8 netboot server, however I find that the "diskless" function is not working as expected.
    When netbooted, normally we can use Disk Utility to erase, partition, zero local drive as needed, but with this image we're getting "Disk cannot be unmounted" error. This is just what happens when diskless is not enabled on previous netboot images.
    Anyone else able to utilize Disk Utility with a 10.6.1 netboot image?

    Also, way back, we used to have to resize the netboot volume to prevent "out of space" errors when imaging... or are these errors another symptom of the "diskless" issue?

    On a positive note, my 10.6 nbi is 4.8 GB, compared to the gargantuan 11.29 GB 10.5 nbi !

    I've got a 10.6.1 nbi working just fine and able to do imaging with it, but it's booting from a 10.6 server... don't know if that's the difference that makes it work nor not.
