Sequel to https://fedoramagazine.org/use-lvm-upgrade-fedora/ but for Btrfs
It is considerably easier to use btrfs snapshots for a fallback instead of LVM in case system-upgrade goes south. (As indeed it did when upgrading my OG Pinebook.) It might not even need the “experts only” disclaimer. In the simplest form, you create a subvol snapshot and do a normal system-upgrade. To fallback, edit the grub entry for the previous kernel to use the snapshot. I could cover cloning the default grub entry with grubby for the fallback, but probably just exhort readers to practice editing grub entries at boot time.
Does that mean go ahead? Or just a vote? nvm, I see R E creates a pagure issue as the next step.
+1 I’ve created Pagure ticket #193 for your article and assigned it to you.
If I may suggest something, it might be good to reconsider the title. As it stands it could be interpreted as using Btrfs to actually do the upgrade. I believe you are describing setting up a fallback or recovery in case something goes awry.
Please use comments on ticket #193 if you have questions or need to communicate with the editors about anything.
The overall work flow is described at this link.
When you have it ready to review in the Fedora Magazine WordPress site, please leave a comment in this ticket with a preview link and we will start the review process.
This means “go ahead”. Thanks for volunteering
I had a different title for the LVM article, but the Editor changed it. I agree it should have “fallback” or similar in there somehow.
