From: Christopher Larson <chris_lar...@mentor.com>
On sysvinit systems, volatiles is configured to make /etc/resolv.conf symlink
to a file in a volatile path, which lets us write to /etc/resolv.conf for
read-only-rootfs. For systemd, this isn't set up unless we enable
systemd-resolved, which we don't by default. When it's not enabled, create the
/etc/resolv.conf symlink and ensure the volatile path is created on boot with
tmpfiles.d.
