Tips on shrinking netboot image

Greetings.

I was wondering if any of you have tips on shrinking the netboot image that Casper Imaging runs off of. I made a minimal leopard install (ie. OS with no printer drivers, languages, or X11) and created a netinstall set with Casper NetInstal Creator 2.02 (from the Resource Kit). The resulting spareimage file in the .nbi directory is 6.76 GB.

On an iBook G4 that I've netbooted in verbose mode, it is saying, "uid 0 on /private/tmp: file system full", and it seems plausible that a smaller netinstall set might alleviate this.

Cheers,
Clinton Blackmore

    i just deleted all the unnecessary apps out of the application and the utilities folder before running thr net install creatir i think i left terminal and system prefs. everything works fine since casper imaging takes care of everything.

    This is what I remove. I don't recommend removing all of this stuff unless you're sure you don't need it, but for what I do I remove all the following and it shaves about 2.5 GB off the install.

    /Applications (Erase all Except Casper Imaging, System Preferences, Utilities)
    /Applications/Utilities (Erase all except Activity Monitor, Console, Disk Utility, System Profiler, Terminal)
    /Library/Application Support
    /Library/Desktop Pictures
    /Library/Dictionaries

    Three updates to this problem:

    - Using the NetInstall Creator 3.0 from the June 2009 resource kit will allow the system to netboot.
    - I've been told that having unnecessary files in your netboot image does not actually slow down the bootup process.
    - It turns out this machine only had 128 MB of RAM. I'm amazed it would boot into Leopard at all!
