Hmm, config.txt is fairly wide ranging, dealing with things the user generally shouldn't change (which kernel to boot, which initramfs to load) to things they're very likely to change (whether the camera firmware is enabled, overlays to load for things like the fan-shim).
Unfortunately the lines that may need altering may well be spread out across the file so there's not necessarily an ideal location to place a comment but I could certainly adjust things to output such a comment prior to the first line changed and link to this bug. I'll propose a merge in a bit with the suggestions. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1923673 Title: Rewrite fkms overlay to kms overlay on upgrade of desktop pi image To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1923673/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
