From 9a787dd105edeea5fdb309a50f2b47155937c5ed Mon Sep 17 00:00:00 2001 From: BlackDex Date: Tue, 19 Jul 2022 18:39:42 +0200 Subject: [PATCH] Fix persistent folder check within containers The previous persistent folder check worked by checking if a file exists. If you used a bind-mount, then this file is not there. But when using a docker/podman volume those files are copied, and caused the container to not start. This change checks the `/proc/self/mountinfo` for a specific patern to see if the data folder is persistent or not.
