Mick, Application Control inventory is a factor of file location and checksum(along with tons of meta data about the files which is system specific). In our experience, however may the 2 images look alike on the surface, this combination for the OS files is never the same.
A quick and easy way to validate this is to put the inventory off the gold image's system volume on the system volume of another system(based off that image) and run command >sadmin check (https://kc.mcafee.com/resources/sites/MCAFEE/content/live/PRODUCT_DOCUMENTATION/ 24000/PD24673/en_US/mac_610_standalone_C…)
If you see no filenames dumped after running this command, you can think about copying the inventory(because the 2 images are actually same). However, if even one of the system files is different or left over, there can be issues in enable mode.
Hope this explains why we do not recommend copying inventories across the systems.
Thanks for the feedback neelima. We did do some testing and yes your right, while on the surface the systems may be running the same image there are enough variations in binaries that we run into a few issues. Instead we opted to look for ways to improve the solidification time given the hardware limitations in play. We found that by adding the Solidcore service binary scsrvc.exe into a VSE On-Access Low Risk Processes Policy so it was excluded from AV scanning. We also removed all Windows hotfix roll-back directories in C:\Windows\. I'm looking forward to the next major MAC release as I believe the functionality to exclude directories from the solidification process is being incorporated. With just those two actions alone we were able to achieve a halving of the solidification time from around 40 minutes to 20 minutes which my client has conceded they can live with.
Mick, I would like to discuss other threads also. Can you message me your contact info so that I can setup a call?
