Ubuntu Remastering - Waikato Linux Users Group You have two options; either do your edits in the 'main' respository on the CD, or create an 'extras' repository. Either way, you will have to create your own ubuntu-keyring package; if you use an 'extras' repository then you can just put a higher numbered version in there, which the installer will prefer. Since Dapper, a "server" CD has been available, which solves the "graphical cruft" problem. I recommend preseeding that for server/firewall installs. remasteringubuntuwlugwiki in WORK > TUTS > UBUNTU debwith worktutsubuntudeboptionseditsmainrespository
