Hi - new here : ) Been a long-time user of LTSB 2016 and now LTSC 2019. Have been looking into fiddling with ISO files to try and make a modular (to my own discretion) LTSC ISO file that is capable of gaining future feature updates (before LTSC 2021/2). Is it possible to compile a complete, bootable .ESD/Decryptable .ESD > .WIM file that is missing base UUP/.ESD components? So, for example, if you want to make your own UUP into ISO, you need to have all of the relevant UUP/.ESD files present together to make a complete, bootable .ESD. Is there a way to edit the dependency on whether or not all base .ESDs must be present in order to compile a full .ESD compilation, or are they all part of one another, kind of like how archives can be split into mutually dependent parts?
