If someone comes to me today and says "I want to help btrfs be successful in Fedora", I'd like to know where to point them besides just suggesting they get added on the btrfs kernel alias. Forgive me, but I had missed this in the sea of other messages (this thread is long and crazy now!). The Fedora Btrfs folks over the past few years have implemented the following: * Developed a DNF plugin to invoke snapper correctly for full system snapshots * Ported over the change set from SUSE to the Fedora grub2 package to support btrfs boot to snapshot * Fixed grubby to handle snapshot menu items for grub (this is kind of deprecated with BLS, though) The things that I'm looking to do: * Develop a libdnf plugin to replace the existing DNF snapper plugin (so that PackageKit is also covered) * Adapt the boot to snapshot stuff to use BLS (with boom, presumably?) The things I've been pushing off (for obvious reasons): * Enable Anaconda to allow /boot to be a btrfs subvolume (PR is in limbo...) * Ensure Anaconda configures snapper automatically when btrfs rootfs is selected * Design a sensible default btrfs layout (perhaps based on the current openSUSE one?) The mid-/long-term things I'm thinking of: * Consideration of moving the rpmdb to /usr/lib/sysimage/rpm (unifying standard Fedora and OSTree Fedora...) * A libdnf plugin to implement atomic package management using btrfs snapshots (like transactional-update, except done properly...) That's basically the full scope of the Btrfs enablement work I've planned right now. -- 真実はいつも一つ！/ Always, there's only one truth! _______________________________________________ test mailing list -- test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to test-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@xxxxxxxxxxxxxxxxxxxxxxx
