There's A Proposal To Switch Fedora 33 On The Desktop To Using Btrfs
There is a new proposal to use Btrfs as the default file-system for desktop variants starting with Fedora 33. This proposal is being backed by various Fedora developers, Facebook, and other stakeholders in believing Btrfs is more featureful than the current EXT4 while now is stable enough following years of testing.
Btrfs supports various features like solid-state drive optimizations, transparent compression support, native RAID capabilities, better handling when running out of disk space, online shrink/grow, and much more.
The proposal was sent out today to the Fedora devel mailing list. Understandably there are users and developers on both sides on whether this is a good idea. It will be interesting to see if any consensus is reached and ultimately whether the Fedora Engineering and Steering Committee decides to approve this change for using Btrfs by default on Fedora desktop installs.
