Btrfs: The Butter of Fedora

on YouTube ↗20m

" summary

Btrfs becomes default on Fedora 33 for desktop variants with subvolumes and snapshot workflows exposed; Fedora 34 turns on Zstandard compression on by default and uses LUKS for full‑disk encryption (no partial‑disk encryption yet) while the boot still on ext4 by default. Planned Fedora 35 work adds online native LUKS, osbuild subvolume support, boot‑to‑snapshot and atomic updates via packagekit/microdnf with transferable snapshots. Snapper and btrfs send/receive are used for rollbacks and backups; kernel 5.10/5.11 yields 50–125% faster in 5.10/5.11 IO in many workloads.
