Up to now there was no clear ordering of confext and sysext units. Normally, configuration should be able to influence the behavior of services (config files or unit drop-ins), so it makes sense to order confext before sysext. The mounting from the initrd for the final system makes this less important together with the fact that live merges/ refreshes can encode unit restarts now. Yet I think it's better to know what gets merged first and if wanted one can avoid encoding restarts if one doesn't care about later live content changes. Where it matters more for me is consistent behavior for the refresh check during boot for non-verity images because they get compared by file handle and mount ID which means whether the overlay was set up or not determines the identity and decides if we do a refresh or not and this should not vary by boot merely due to timing or other dependencies impacting the ordering. (Note that one extension type shipping another extension type is not the reason for the ordering and these cycles should be avoided because they never free the mounts and backing loop devices.)
