I have been using openSUSE for some time and I love how everything can be managed by almost any user.
But I am considering that KDE or GNOME cannot hold responsibility for system wide modifications like UPDATING or CONFIGURATION and BACKUP.
Some processes are critical and if something gets corrupted then we have a really messy situation.
Sometimes this processes are long so since DE’s sometimes have problems and the whole thing can crash or freeze then we should be able to let the computer finish those things and then be able to reboot without so much hassle.
Hope this helps and TY for your attention. BD
