I'm manually creating an image on an external drive and I'm going to use Carbon Copy Cloner to clone it to new MacBook Pro's. Should I install Jamf on the image? If I do that what should I do after I clone to the new Mac? Just run sudo jamf policy? or more than that?
Do not enroll in Jamf before capturing the image. If you want to streamline things, you can put a copy of the quickadd on the image so you just need to install it.
Never clone applications that have any sort of unique relationship with a database. You'll get all sorts of unwanted behavior.
Honestly, you're going the wrong direction anyway. Monolithic imaging has been mostly dead for a while, and it's only getting deader. It's an archaic approach that has all sorts of problems.
