Well, it doesn't really matter how you reboot, as long as you do it somehow. Well, and actually, if people decide not to reboot at all it's OK too i guess, "systemctl isolate system-update.target" should work too. However, I'd always recommend rebooting first, so that the system is in a really well defined state when the update is attempted. > 2) Did anyone consider a plan to do updates on ext4 and btrfs > differently?

If source based distros want to implement this I'd probably recommend them to compile everything in the system, and only do the final step, the installation as part of the system-update step.
