Callouts

¹ - Image label as presented be the Marketplace API
² - The value of the build_date field in the /etc/cloud/scw-build.info file
³ - The value of the build_tag field in the /etc/cloud/scw-build.info file
⁴ - Instance is reachable but the DNS resolution is not working
⁵ - Same as 4 + only the first IPv6 gets configured automatically
⁶ - The Flexible IP attachment order matters: this only works if at least one routed_ipv6 is attached to the Instance after at least one routed_ipv4 has been attached
⁷ - The version of cloud-init is too old to support such a configuration
