Subject: [pve-devel] [PATCH container] apply pending mountpoint: also hotplug non-volume mount points
Date: Mon, 8 Aug 2022 14:36:42 +0200 [thread overview]
Message-ID: <20220808123642.2412163-1-f.ebner@proxmox.com> (raw)
Previously, bind and device mount points were applied to the
configuration, but not actually hot-plugged/mounted, causing a
mismatch for running containers.
