I recently built a woody DVD-R image and wanted to share my experiences with the group. (The code I used will appear on my CD hacks area at http://www.lordsutch.com/cds/debian-cd/ sometime soon... nag me if you don't see it by Monday.)
The main issue I faced was that the shell's math seems to be limited to 32 bit integers, which broke some of my disk sizing code (and may also break bits of the standard scripts). I decided to change all the code to use kilobytes instead of bytes, which resolved that problem. I also had to hack my list2cds-cram code to use kilobytes (I could have used Python longs instead, but with the 2kbyte rounding I decided that there was no need to keep track of bytes any more). I didn't hack the source disk building code, but it probably would need it too. (You can't put source and binaries on the same DVD; woody's binaries took up 3.9 gigabytes on Intel, just including main and non-US/main. Double-sided media might work nice for this, if you can get it...) I was able to successfully write the ISO image at 2x to a Pioneer DVD-R drive using the free DVD-R patch (http://www.abcpages.com/~mache/cdrecord-dvd.html) for cdrecord. The DVD-R was readable on both the drive that wrote it and the DVD-ROM on my Toshiba laptop. (The laptop was also able to boot from the DVD-R.) This was a one-off deal to test the DVD drive for my employers; I may consider adding a DVD-R to my CD production farm if I can locate a reasonably-priced 2x unit. Anyway, I hope this info helps anyone who's considering building Debian DVDs. I should have the code on the website in the next couple of days.
