Give users an indication of what distro platforms the project intends to be buildable on. This policy will be used to decide when it is appropriate to increase the minimum required versions of external dependancies.
While this sounds like a good idea at first, being so specific about versions makes it a very bad one IMO. i-e this list will get outdated all the time and none of us will remember to update it often enough for it to be useful. Also IMO selecting a few downstreams isn't a good idea in upstream project. We really should be distro-agnostic and libosinfo should be buildable on any GNU/Linux distro. The idea here is to convey the message "We do care a lot about individual distros" but unless this list is a long one, we are actually saying "We only care of these distros". As I said before, I think we only need to define a time frame in upstream (i-e we guarantee we won't bump any dep to anything newer than X amount of time) and be done with it. No need to focus on any particular distros, just provide enough time for distros. In worse case, they'd have to cherry-pick fixes from newer version of software, which is what long-term support downstream typically imply anyway.

Based on this classification, the libvirt-glib +project will generally aim to ensure build support for + + - Most recent 2 releases of short lifetime distros + - Most recent major release of extended lifetime distros, + with most recent 2 minor updates + +The project will consider RHEL, Fedora, Ubuntu LTS, Ubuntu, OpenSUSE +and SUSE (SLES/SLED) distros to be a representative subset of distros +when determining min required versions of external deps, as other distros +of similar release vintage will typically have similar versions. In the +case of Debian, the project may at times choose to require use of an +update from the backports repository. + +As an example, as of July 1st 2015 this policy would imply that the +following distros are officially targetted as buildable platforms: + + - RHEL: 7.1, 7.2 + - Fedora: 21, 22 + - Ubuntu LTS: 14.04 (Trusty) + - Ubuntu: 14.10 (Utopic), 15.04 (Vivid) + - Suse: 12.0 + - OpenSUSE: 13.1, 13.2 + - Debian: 8.0 (Jessie) + +At any time, it may be possible to build on versions of distros +that are older than those implied by this policy, but the project +will not guarantee this remains the case in future releases.
