GPL and storage requirements

[Mike McGrath]

Matt Domsch recently posted this to the Fedora Infrastructure List:

Everything (Core + Extras, FC 1 through 6, 7test[12], development,
updates, repodata): 492GB
FC1: 21.5GB
FC2: 35.5GB
FC3: 33.1GB
FC4: 52.4GB
FC5: 69.6GB
FC6: 77.5GB
development: 50.8GB

FC+E6/i386: 22.6GB
FC+E6/ppc: 23.5GB
FC+E6/x86_64: 24.4GB
FC+E6/source: 5.1GB

FC6test2: 26.8GB

so we're already expecting mirrors to carry ~25GB per arch per release
or thereabouts.

If we continue with 3 arches, 2 releases per year, that's at least 150GB
per year growth.  If we add arches, Unity respins, more CD/DVD objects,
and the like, it'll grow faster.

=============================

My question is, who knows the finer details of what the GPL requires us 
to keep?
