[Casper] Image too big?

[Ernst, Craig S.]

Quicker and easier because of the block copy you mean? I'd still prefer a virgin OS...just my opinion.

I like the idea of layering Apps on top of the image, but for things like Office 08, iLife and iWork its quicker and easier to just have them in the image.  We have thousands of computers to image over the summer and we use multicast so we can do a high number of computers at once with limited server resources.

I do have lots of other packages that we install via policy and casper remote after the computers are imaged.

We do all of our imaging from netboot using Casper Imaging.

You called your image "monolithic"  in your email, which leads me to understand that you have the OS plus all "common" applications installed in the image and that is what you are laying down on machines.  Like Jared said, pull out all of those apps and install them Self Service.

My OS image is just that, the OS, with nothing else.  I use InstaDMG to build the OS image, then use Casper configurations to push the "common" applications, with the exception of the Adobe suite.  I push the Adobe suite by a login policy.  I put machines I am imaging into a Smart Group by naming them a certain way so they automatically get added to a "Post Image" policy that installs Adobe CS3 and all updates.

That's what I was wondering...why is it so big? Are you talking just your base OS package or everything that gets installed with Casper Imaging? Are you caching packages locally then I assume?

My OS is around 3.57GB. I've stripped out printer drivers to be packages installed later as needed, as well as the languages.

Are you imaging from a Restore partition or while NetBooted?

Slim down your image and let people install from Self Service

Our base (somewhat monolithic) image has gotten too big to put on a 40GB hard drive.  The compressed image file is just over 13GB and is around 25GB once installed.  We are imaging with Casper Imaging using both standard imaging and multicast streams.  Both are having this same problem.  Is there any easy fix to this?  Obviously the 25GB image will work on a 40GB drive, but I no longer have an easy way to get the image onto the drive.
