+# Vendored: SysGuides snapper scripts for Fedora
+
+Source: https://github.com/SysGuides/sysguides-snapper-fedora (MIT, Madhu Desai / SysGuides)
+
+Vendored (2026-10-27, upstream commit 0a28eb4) so setup does not depend on an
+external repo at runtime. `lib/common.sh:setup_snapper` installs:
+
+- scripts/snapper-*.sh  -> /usr/local/bin/ (DNF5 pre/post snapshot actions)
+- config/snapper.actions -> /etc/dnf/libdnf5-plugins/actions.d/
+
+To update: re-fetch from upstream, diff, commit here.
