Fedora 33 Making Progress With Their Btrfs-By-Default On The Desktop
While the Fedora Engineering and Steering Committee has already approved using Btrfs for desktop spins by default with Fedora 33, a lot of work still is being done to make that a reality for the debut of F33 this autumn.
The recent work includes:
- Updating the Anaconda installer to default to Btrfs for automatic partitioning with all desktop install media.
- Libvirtd patches that will set "nodatacow" on VM image containing directories if running on Btrfs. This is for disabling Copy-on-Write functionality for directories with virtual machine images where the performance is hurt and the CoW functionality less useful.
- Various Btrfs kernel patches have been picked up for the F33 kernel.
- The Btrfs file-system driver is now built into the kernel rather than as a module.
- The Red Hat Continuous Kernel Integration project has added Btrfs to their regular testing.
- Documentation improvements.
- Other fixes and preparations.
