Dear Petter,
I think you are using a valid Maximum Likelihood Estimation (MLE):
debian-edu-etch-source-DVD-3.0r0.iso 0,12 8
debian-edu-etch-powerpc-netinst-3.0r0.iso 0,06 4
debian-edu-etch-i386-netinst-3.0r0.iso 2,15 138
debian-edu-etch-*-DVD-3.0r0.iso 97,67 6278
Total 100,00 6428
Given 142 downloads of netinst CDs resulting in 48+14=62 installations
(ratio: 0.44), and persuming the same download-install ratio for 6278
DVD downloads observed, we get even 2741 installations resulting from
that.
There might be only two flaws: The ratio of netinstallations might
deviate from DVD installs, and your netinstall-logger will also observe
installations from CDs that have been distributed from foreign sources
(direct copies, mirrors etc.). Thinking about it, netinst-CD will
mostly be used with clients (many), DVDs will mostly be used for
servers (few).
Let's hope that PopCon tells us more one day... ;)
Kind regards
Ralf.
