Most of the time we delete everything but Casper Imaging, Terminal, Disk Utility, and Safari from the Apps and Utilities folders.

Then run software update.Ģ) Manually enable the root account, set it to auto login and set the newest version of Casper Imaging to launch at login for Root.ģ) Launch Casper imaging and make sure it connects to the JSSĤ) Remove all uneeded apps.
#DISKWARRIOR 4.4 DMG INSTALL#
Here is the basic work flow:ġ) Install Lion base, or grab a new out-of-the-box Mac on the newest hardware available. It doesn't take too long and it is something we can kick off in background while we work on other things. So, when I am onsite and the customer expresses a need for a thinned out netboot image I just create it manually. Going out and performing Jump Starts with our customer base, I am finding more and more this is requested. Each new OS from Apple gets bigger and bigger on disk. Under Lion, its harder to get a really slim image than it was under 10.6 and lower. Basically anything that is not strictly required for the OS to function. Back under 10.6 though, I used to use the NetInstall Creator, which was handy since it did a lot of those above steps for you.Įdit: Mixed in the middle of those steps which I didn't list was removing as much fluff from the OS as possible without breaking it, extra apps, language localizations, desktop images, screensavers, etc. I'm not really clear what the Automator action does, if anything, outside of some of those steps. I then captured that in Composer and ran it through SIU to make my final NBI. In most cases when i've created a Lion Netboot image for use with Casper Imaging, I just did it manually, installing a minimal base OS on my latest & greatest piece of hardware, installing all updates, enabling the root user, copying over the Casper Imaging.app, logging in as root, launching Casper Imaging and setting the prefs, (optionally) adding a custom desktop background, set the root account to 'auto login' and finally, setting Casper Imaging to open as a login item. What is the size of your NBI folder after running through SIU? What is the size of your Minimal OS Image after configuring the root user and adding Casper Imaging? Once I had that 5GB image, I ran Apple's System Image Utility (SIU) and used the Casper Automator action that is part of the latest Resource Kit to create the NetBoot image.
I followed the instructions, setting up a machine with a minimal install of 10.7.3 (removed apps from Applications folder that do not need to be there), enabled the root user, logged in as root, enabled auto login for root, set the computer name, added Casper Imaging, added CI to the startup items, reboot to test, and then finally booted off of an external drive to capture that OS image via Composer. Once you have that minimal OS you should then follow the steps in the bottom part of the page to create the root user, add Casper Imaging, and make sure the system logs in and starts Casper Imaging on boot up.
The first part, creating the minimal OS, is just the beginning. In reality the two sections of that article ( ) should be viewed as one.
