no, the worst case is this:
I had this kind of fun problem upgrading F25 -> F26. I was lazy and didn't
want to reboot so I was just running dnf distro-sync in a gnome-terminal
session. I've upgrade this way since F6 and mostly it just works, but
forgot to nohup it. About 1/3 of the way through installing new packages,
something causes gnome-terminal to die. I had to write a script to read
the dnf planned transaction log and finish installing and erasing remaining
packages, and manually run any %posttrans scripts.
So yeah, even with latest Fedora things can & do go horribly wrong if you
ignore the advice to not run upgrades from a live system.
