Recovering from Btrfs Boot Failures Using GUI Tools on Fedora

on
By the end of this guide the reader will be able to identify a Btrfs‑based Fedora installation, boot from a live USB, list and restore snapshots using the graphical utilities btrfs‑assistant and snapper, and verify that the system returns to a functional state without resorting to the command line. Understanding the Btrfs Layout Used by Fedora Fedora Workstation and Fedora KDE install the root filesystem as a single Btrfs partition that contains two default sub‑volumes. One sub‑volume holds the traditional “/” hierarchy, while the second is dedicated to /var/lib/machines . The latter exists to keep container images out of snapshot operations; it remains empty on systems that do not run virtual machines. Because Btrfs stores data in sub‑volumes rather than separate partitions, a snapshot captures the state of an entire sub‑volume at a point in time. The installer (Anaconda) automatically registers these sub‑volumes with the snapper service. Snapper maintains a series of read‑only ...
