Thanks for the warm welcome Mark. Matt, I CCed you because I wasn't subscribed to ubuntu-devel yet so couldn't reply directly to your mail there.
First of all, some new data and a word of caution: Today I used MD5 hashes to see if there were any duplicate PNGs in my collection and indeed there were quite a lot: out of all 12.023 images, there were 4.514 duplicates (37.5% of the total count). Using OpenOffice.org Calc I calculated the savings of getting rid of the duplicates: 10.545.222 bytes (10 Mb). At this point I got suspicious and thought about mistakes I could have made during my initial data gathering. I thought about the effect of symlinks in the directory structure and although "find" doesn't follow symlinks when they're directories, "find" does report symlinked files. I will try to investigate whether or not symlinks are causing the many duplicate image files and report back once I have the new, possibly corrected, numbers. Matt, I also wanted to address your comment about not gaining much space on the CDs: in my original mail I wrote that the savings are roughly eight megabytes when using bzip2 to compress all PNGs into a single archive. Eight megabytes is quite a lot I think, especially because this makes room for some new or updated packages on the CD. To summarize: before we make any decisions on my initial analysis I'd like to investigate the correctness of the numbers I provided, I hope this won't pose a problem. The timespan for this is about two or three days. In the meantime, I'll be looking forward to discussing the matter on ubuntu-art and ubuntu-devel with anyone interested in this subject.
