From 633d5f1f8b8844d6e2fb3e2593768360c889ed76 Mon Sep 17 00:00:00 2001 From: Valentin Rothberg Date: Wed, 18 May 2022 11:34:13 +0200 Subject: fix --init with /dev bind mount The init binary until now has been bind-mounted to /dev/init which breaks when bind-mounting to /dev. Instead mount the init to /run/podman-init. The reasoning for using /run is that it is already used for other runtime data such as secrets.
