I'm trying to determine the level of support enjoyed by various software packages across all major Linux distributions. That is, for a given package, find which distros include it in the default installation, and if so, what version they include. For both new distro releases, and older ones.
A few distros actually publish a list (e.g. D.S.L.), but thats pretty rare. Debian-based distros seem to have a comprehensive online database of packages and their metadata, but whether a package gets installed by default doesn't seem to be shown.
Distrowatch does something very close to what I want, but a) it isn't tracking all the packages I'm interested in, and b) it doesn't seem to mention whether a package is merely available in a distribution, or is included in the distributions default base install.
I could of course download and install each of the distributions I'm interested in just to check to see if the package gets installed, but that would take days, and is a pretty inefficient use of resources.
