From df99522c6794cbf9ea77c4c314dadf9e9b5b2a54 Mon Sep 17 00:00:00 2001 From: Daniel J Walsh Date: Mon, 24 Dec 2018 06:55:24 -0500 Subject: Fixes to handle /dev/shm correctly. We had two problems with /dev/shm, first, you mount the container read/only then /dev/shm was mounted read/only. This is a bug a tmpfs directory should be read/write within a read-only container. The second problem is we were ignoring users mounted /dev/shm from the host. If user specified podman run -d -v /dev/shm:/dev/shm ... We were dropping this mount and still using the internal mount.
