I didn't define Debian situation very well in the support policy because I didn't realize it had separate normal and LTS EOL dates. I had originally thought it was LTS only. In libvirt we have since clarified the language I originally wrote (and then copied to QEMU), to remove the LTS distinction. Instead libvirt now says: "The project aims to support the most recent major version at all times. Support for the previous major version will be dropped 2 years after the new major version is released or when the vendor itself drops support, whichever comes first. In this context, third-party efforts to extend the lifetime of a distro are not considered, even when they are endorsed by the vendor (eg. Debian LTS)." I'd suggest we copy this updated terminolgy into QEMU as it simplifies the current language used.
