We’re only one month away from the public release of Fedora 33, which represents a massive shift for the Red Hat-backed Linux distribution. Fedora has been using ext filesystems since Fedora Core 1; switching to BTRFS as the default is kind of a big deal. Thankfully, the Fedora 33 Beta is now live for everyone. Ready to test drive the benefits this copy-on-write filesystem brings to the party?
For GNOME desktop fans, there’s a lot to appreciate going into the Fedora 33 Beta. This ushers in GNOME 3.38 which now includes a Welcome Tour to get newer users up to speed on key desktop functionality, improved screen recording and multi-monitor support, and a bunch of performance improvements.
A detail getting less exposure but one well worth testing and benchmarking is the inclusion of thermald in the default install. Theoretically this should deliver better thermal management and peak performance for Intel CPU users.
The headlining feature this time around, however, is undoubtedly the inclusion of BTRFS as the default filesystem. This change applies to every desktop variant of Fedora Workstation — so yep, that includes the spins.
“BTRFS offers some really compelling features for users, including transparent compression and copy-on-write.”
Matthew Miller, Fedora Project Leader
It also supports RAID, online resizing and defragmentation, plus lets users create both readable and writable snapshots, which appear as normal directories in the filesystem. The biggest advantage here is for people, well, like me, who may make a rather huge mistake at some point and need to roll things back to a previous, properly working state.
I first experienced that particular magic when using openSUSE — a distro that adopted BTRFS way back in 2013 — and it was a life-saver.
Fedora Project Leader Matthew Miller says that Fedora 33 is “defaulting to the basic features of BTRFS, but we’ll build out the default feature set to include more goodies in future releases.”
It will be very interesting to see what improvements come to BTRFS now that the weight of Red Hat engineers is behind it.
