I use PCLinuxOS as my primary Linux OS. They are a bit conservative to adapt new updates until they are sure of stability because of rolling nature. KDE is still at 5 there. Heard about Neon and wanted to try KDE 6. I find that they have adopted Windows style approach to updates where we need to reboot to apply the updates and we cannot do anything on the system while the updates are processing. Recently managed to install Fedora because I heard that their EFI is secured or something and can survive clobbering by Windows updates in a dual boot setup. But they also seem to have gone with offline updates.

Are offline updates necessary due to them using SystemD or is the Linux world in general moving in this direction?
