Package: live-build Version: 3.0~a17-1 Severity: wishlist User: [email protected] Usertags: origin-ubuntu oneiric
I'm looking for some guidance on one of the remaining major pieces involved in making live-build usable for official Ubuntu live filesystem builds. Most package installation in our current live filesystem builds is done in two stages. The first corresponds to the packages that should be copied to an installed system when installing from the live CD, and the second corresponds to the packages that may need to be removed from the installed system: this includes live CD boot infrastructure, the installer itself, and other bits and pieces such as language packs. At the end of the first stage, we write out filesystem.manifest-desktop; at the end of the second stage, we write out filesystem.manifest. After copying files to disk, the installer takes the set of packages in filesystem.manifest but not in filesystem.manifest-desktop, eliminates any packages from that set that some bit of the installer explicitly asked to keep (for example, we might as well keep the language packs corresponding to the user's language rather than making them reinstall them from the network), and removes that set of packages from disk. live-build doesn't currently support this kind of two-stage installation except by means of local hooks, and as explained in http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=627332#25 I would like to find a way to do this without local hooks. I'm happy to do the implementation work, but do you have any ideas on a nice way to do this within the structure of live-build? There is of course the possibility of not bothering with a two-stage installation, and instead computing filesystem.manifest-desktop independently. I'm reluctant to take this approach because it would carry risk of archive skew and/or simple coding errors resulting in filesystem.manifest-desktop not matching what apt would have installed at that point in a hypothetical two-stage installation; but it's an option if you think this just won't fit.
