💖 NAME 💖

okay so dnf-snapper is the DNF snapper Plugin, and this is its dnf-snapper(8) page from the dnf-plugins-extras crew. ✨

It creates a pair of snapshots of root filesystem, bestie. One snapshot is created just before the transaction run (Pre) — meaning after a successful transaction check and successful transaction test. And another snapshot is created when the transaction has finished (Post). The user is not supposed to interact with the plugin in any way. No cap, it just does its thing. 🫶

⚠️ WARNING: There is no mechanism to ensure data consistency during creating a snapshot. Files which are written at the same time as snapshot is created (eg. database files) can be corrupted or partially written in snapshot. Restoring such files will cause problems. Moreover, some system files must never be restored. Recommended is to only restore files that belong to the action you want to revert.

🌸 CONFIGURATION 🌸

The config lives at /etc/dnf/plugins/snapper.conf, iykyk. 🎀

🎀 [main] section optional parameters 🎀

  • enabled — boolean, default: True. Specifies whether the plugin is enabled.
  • snapper_config — string, default: root. Specifies which snapper config should be used when taking snapshots.
