Hi, i assume https://www.debian.org/CD/vendors/info is the complete official rule set for vendors.
If you plan to burn debian-live-10.0.0-amd64-standard.iso to 900 MB CD-R, i would be interested to learn whether this is possible with xorriso and how the medium is described by xorriso -outdev /dev/sr0 -toc All other Debian ISO images either need DVD or BD media or they are quite useless without downloading more Debian packages from a network. I assume "Debian CD" also means Debian USB stick. The installation ISOs "debian-*-1.iso" from https://cdimage.debian.org/debian-cd/current/amd64/jigdo-16G/ https://cdimage.debian.org/debian-cd/current/amd64/jigdo-bd/ https://cdimage.debian.org/debian-cd/current/amd64/jigdo-dlbd/ would make bootable USB sticks with quite a wealth of installable packages on them. (We could discuss improvements of their partition table if the current layout gets bad reviews from the customers.) Have a nice day :) Thomas
