From 0182e119516a14d49778bec94d3aeb9ce5742a83 Mon Sep 17 00:00:00 2001
From: David P <megver83@parabola.nu>

Subject: [PATCH] OpenRC scripts: add configuration file

This allows users to customize the snapshots path to work with, e.g., snapper.
If no path is configured, it will default to timeshift.
