From 6d394f0e474417892645a4d0b4a786cd733f0e8c Mon Sep 17 00:00:00 2001
From: Daniel J Walsh <dwalsh@redhat.com>

Subject: Create the /etc/mtab file if does not exists

We should create the /etc/mtab->/proc/mountinfo link
so that mount command will work within the container.

Docker does this by default.

Fixes: https://github.com/containers/podman/issues/10263
