To create the CD I basically took the xubuntu alternate cd. Then I copied over the whole ISO and put it into one directory(lets call it cd-img). Replaced the isolinux folder with the fancy isolinux folder from the livecd with the cool looking logo png and where you can set language with F2 and with F3 the keymap and so on. The first thing that I did afterwards was taking the xubuntu.preseed file that ships with the xubuntu-10.10-alternate-i386.iso and changing it basically from xubuntu-desktop to lubuntu-desktop(I know there is a lubuntu.seed file on the live cd but I took the one from the other alternate cds as they were more entries and I didn't want to mess ups things). Then I put this preseed file back to my copy of the minimal install cd(so the cd-img folder) into the preseed folder. I did change the txt.cfg file in isolinux so that the default option would boot with the preseed file option of the lubuntu.seed . Then the little bit more tricky part create a repository. For creating this repository I know that I need every package that needs to be installed when installing lubuntu-desktop. Every means every , so also xorg and those other stuffs. As I had a Minimal Install ISO aswell I simply created a minimal installed cli only system in virtualbox and apt-get install(ed) lubuntu-desktop. All the required deb files are stored in /var/cache/apt/. The only thing to do now is getting those deb files outside the virtual machine. Then there is a cool package called apt-move which is pretty handy as it can automatically copy or move those deb files in a repository like hierarchical folder view. So it will create automatically the structure of a repository that you need, by putting in lubuntu-desktop for example in a pool/l/lubuntu-meta/lubuntu-desktop_xXX-i386.deb file/folder structure. By default this repository structure will be put into /mirrors/debian so you need root right to run apt-move. But I guess the default folder is changeable I just was to lazy to read the manpage ;) Then we copy over the pool directory to the cd-img folder. Again me as being lazy I didn't overwrite all the packages that where already in the xubuntu pool directory (they can be deleted later I guess or you can delete the whole pool directory with the exception of the udeb files. So 'find . -name "*.udeb"' and copy over all udeb files as they are necessary for the installer). Then we have the pool directory almost ready. I had to repackage the ubuntu-keyring package as I don't have the private key to sign the cd and the new repository with official ubuntu keyring. So I downloaded the keyring and added my own private key to it. This step is really important because otherwise the installer won't install if the repo isn't signed. So I repackaged this package and put it into the pool structure unter u/ubuntu-keyring I think it was. That should be all for the pool directory. Basically we need the Release and Packages.gz file for the repository now and sign it. So I created a release.conf file ( storing the basic info like distro name , codename and main + universe repos) and a config file you can see here to get an Idea how it works: http://pastebin.ca/1965874 This is basically the file that will scan the pool files and create the Packages.gz for each repo (means main and universe). As you can see here you need also some override files that you can get from here: http://archive.ubuntu.com/ubuntu/indices As the above config file will only create a package listing for debs I created also a config which scans all the udebs. Here is the config: http://pastebin.ca/1965876 As you can see I basically only replaced the deb with udeb :) Now we have all the config files lets build the packages and release files with: > apt-ftparchive -c /path/to/release.conf generate > ../apt-ftparchive/apt-ftparchive-deb.conf > apt-ftparchive -c /path/to/release.conf generate > ../apt-ftparchive/apt-ftparchive-udeb.conf > apt-ftparchive -c /path/to/release.conf release path/to/cd-img/dists/maverick > > path/to/cd-img/dists/maverick/Release > gpg --default-key "YOURKEYID" --output > path/to/cd-img/dists/maverick/Release.gpg -ba path/to/dists/maverick/Release > #This will sign the Releasefile > Then you can simply update the md5sums.txt : find . -type f -print0 | xargs -0 md5sum > md5sum.txt And this is basically all. Of course you can edit .info directory and the files in there to change them so that the CD Label will change to Lubuntu .... rather then Xubuntu. Rebuild the ISO with mkisofs and you have it ready the Lubuntu Alternate Install CD :) I can also upload my version of the image somewhere so you don't need to do everything by hand ;) Hope that answers you questions. I also didn't found a documentation which explains or does this building of the alternate cd easier. Regards, Leszek
