We're currently using Ubuntu 20.04 as the base for the Ubuntu rootfs, meaning that right now there's no issue with the approach currently taken. However, if we do a bump of an Ubuntu version, we could face issues as the rats-tls package is only provided for Ubuntu 20.04. Signed-off-by: Fabiano Fidêncio <fabiano.fidencio@intel.com>
