That's entirely separate from 'reboot recommended' or 'reboot-required'. There are many cases where a kernel update is pushed out but you might not have any reason to actually boot into it. I quite frequently skip non-security kernel updates if nothing else is actually wrong. We fix bugs in a large number of places, and not all of those places are things your machine might care about. > Unless I misunderstand what you're proposing, in that case, can you > please elaborate? I can try. If all you want to know is whether the most recently installed kernel is running, then you can do that via a script that compares uname to the output of an RPM query on the kernel package. That's fairly trivial to do. (I explicitly say 'most recently installed' because the kernel is odd in that multiple kernels are installed and the most recently installed kernel may actually not be the _newest_ kernel.) However, if you are looking to know whether something (kernel or otherwise) recommends rebooting, then you would want to look at the update metadata. Grub, openssl, glibc, etc can all recommend rebooting for a variety of reasons. >> Otherwise, you run into cases where multiple >> packages want to write/own the file, etc. > > Hence my proposal for a reboot-required package which is the owner and > writes the file. Sure, but that is a lot of hassle that seems unnecessary. Also, because recommend vs. required are different, I would not be willing to e.g. modify the kernel package to Require: reboot-required. It simply isn't an accurate reflection of every possibility. Nor would I be willing to add it in cases where it is required but remove it other times. That's a lot of spec file munging and it would get annoying. >> Also, I think "recommended" is really the appropriate terminology >> here.

Do you care because you want to make sure your software is running with all security fixes? Do you care because you want to simply be running the latest and greatest at all times? Checking the update metadata could probably be done in dnf itself if it isn't already. I believe Software already looks at this flag if you are using that to apply your updates. If you simply want to always be running the latest, then 'dnf update && reboot' solves that need. josh -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://lists.fedoraproject.org/admin/lists/devel@xxxxxxxxxxxxxxxxxxxxxxx
