Hi Tamas,

The Oracle template does both of these for OracleLinux so it should be
possible to do for RedHat/CentOS since they are all very similar,
though I don't think they currently support it. Installing from a
dvd/.iso can be done via --baseurl=file:///mnt. Handling a yum update
inside the container is done by calling the template from a yum plugin
to re-patch the rootfs.
