But now, when you would have done `dnf system-upgrade reboot` on previous upgrades, it's now `dnf offline reboot`. The previous command was quite clear about what it was doing: this new one is rather less so (apparently the `system-upgrade` subcommand doesn't work any more because it no longer exists - I didn't try).
I think DNF5 is new with Fedora 42. DNF now has an "offline" subcommand that allows dnf operations to be deferred until the next boot. Seems useful. I just updated my desktop for Fedora 42. There were a couple of oddities: - I used Gnome "Software" to do the update. When it rebooted to actually install the new packages, I got a blank screen. I let it cook for a while (the fan was running for some of this). Then I sshed in and told it to reboot. That worked. It is possible that this isn't a Fedora issue but a monitor problem. - postfix.system was disabled and not started. I was wondering why I wasn't getting mail. Easily fixed one the problem is discovered. I've upgraded a number of other machines, usually with DNF, but not always. None of those updates produced adventures.
