[10:19] <apw> chiluk_, when a version of nvidia goes complete off support, we transition people to something newer.
[10:20] <apw> chiluk_, we "only" have like on "development" version *5 and two stable versions *0 live at any time, plus there are sometimes a long-term-support branch also *0 where nvidia have dropped a slew of old hardware from later streams.
[10:22] <apw> croraf, that file lists source package handles, that is <series>:<source-package>.  the installation names, the semantic names, move around between packages
[10:23] <apw> croraf, a new source comes into existance often with -wip as its name, testing happens, then it takes over the -edge name.  once full testing and acceptance is complete it takes over the "base" name, and the old source is redundant.  this is done to allow rollback quickly within an sru-cycle.
[10:23] <apw> croraf, that said, the variants (as they are known) for those sources could easily be added to the output.
[18:56] <tomreyn> is this on your radar?
