Use PackageKit instead and reboot when asked. Well it's not always risky, it depends on what's being updated. If it's applications, it's pretty safe unless they're running. There is a qualitative difference between server and workstation, so the warning may be misleading if it exists on server also. > I, for one, *like* not rebooting, and I'm perfectly capable of > rebooting manually if stuff breaks.

You can argue if they're using dnf they should know better, and just accept that things can blow up, or help track them down so if possible this stuff can get fixed. > For server use, I'm not convinced that the offline update mechanism is > supported (at the very least, I have no idea how to trigger it), and > servers have the same issue. PackageKit is installed on server, so while I haven't tested it, it seems plausible it could be used for system updates. But I think the risk here is much less because dnf is a bit more isolated by not running in a GUI Terminal in a user session. But even here, a reboot is expected for many things, there's just no guarantee of state otherwise. I think the thing that's unique with current offline updates compared to other platforms I use is the double reboot. The reboot to get to offline updates target where the update happens, and then a reboot to get back to graphical target. That does seem suboptimal to me, where other platforms just log out the user session, and drop to their reduced function "updates" state to do the update, and then there's one reboot. Anyway, my opinion is that Workstation folks should use Gnome Software to do their updates, and if there's something wonky there, we need to get it fixed. That's the default and primary update method. Within something like 5 minutes of first boot after an installation, PackageKit is already downloading updated packages. Unless that's disabled, a 'dnf update' is going to unnecessarily download those packages in duplicate. -- Chris Murphy _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx
