So I have been challenged to deliver a concept of applying a delta of an image over a pre-imaged machine, to ensure that the first boot of a machine is always on the latest version of an image. The question is, is it possible ?
So the process would be;
1: Pre-imaged machine is installed with a base image
2: Machine then boots to a Ram Disk (PXE/grub to winpe)
3: PE image then applys a Delta of the base image to recently installed machine
4: PE sorts boot drive and restarts machine into latest image available.
1: Software on installed machines is always latest version on first boot
2: Applying delta would be considerably quicker than re-imaging the full drive
3: Delta file size would be considerably smaller than distributing full base image each time
1: Current base image is built via Dism/Imagex - can use WimLib to create Wim Delta
2: Winpe and Grub to apply delta
So - do you guys think this is a possible solution? I am going to start full tests today to see if it works at all.
Secondly is there any better methods of performing a delta upgrade on base images on install? (Time is always very limited on install)
