Netboot Image Creation

Hi All!

New to the Forum... but had a quick question about my new Deploy Studio setup in an environment with about 285 iMacs, ranging from 10.6.8 to 10.8.5 OS X.

I have successfully created my master image for my iMac's and used a thunderbolt drive to restore it to them, one by one. We have a Gigabit network so to transfer the 5.5 GB file only takes about 1:45 seconds, install/reboot totals it to about 3 minutes per computer.

I wanted to use netboot to restore 30-45 computers at a time, providing our network can handle it.

My question:

If I have a mac os x server running 10.8.5, do I have to create my Netboot image on the server that is running 10.8.5 to boot up computers running 10.6.8 via netboot and Ethernet, or must I create the image on the 10.6.8 computer to then boot up other 10.6.8 computers, (providing I transfer it to my server first) all running the same hardware.


I had an image working on my server that was created on the server to boot up clients running 10.6.8 but it unexpectedly stopped working, the client would have the netboot image in Startup Disk Pref Pane and then I would click restart but it would only reboot off of the main HD.

Re: Netboot Image Creation

I would create a 10.6.8 Netboot set on one of your 10.6.8 clients (with the combo update of 10.6.8 installed) using the Setup Assistant and then copy it up to your server's Netboot set repository (/Library/NetBoot/NetBootSP0).  You could use the one created for 10.8.5 on the server, but only if the machines you are imaging can support booting to 10.8.5; otherwise, you need to boot off an older version of the OS (10.6.x, 10.7.x, etc.).  I've had the best luck Netbooting machines off the major OS X version that the machine shipped with initially; sometimes trying to Netboot a machine that shipped with 10.6 off a 10.8 Netboot set seems to not work for me.  This has been particularly true with Mac Pros which seem to love Netbootng from 10.7.5 but not 10.8.5 for some reason.

I keep around one Netboot set for the last versions of 10.5, 10.6, 10.7, and 10.8. just for this purpose (i.e. supporting old hardware).  The oldest ones mainly so we can wipe the hard drives of retired machine using Disk Utility via DS.
