I didn't want to have piuparts use all sources.list entires, since they often have things like debian-multimedia in them. Since apt favors the first one if it can, picking just the first one seemed like a reasonable thing to do, as a guess. If the guess turns out to be wrong, then it's easy enough to override, but it seems to work often enough that it is helpful to guess. > emdebian-tools: > Using 'apt-cache policy' to obtain information > -> told on IRC that it loses port number info. > -> probably picks up security mirrors too, which > can't really be used for running debootstrap. I should have to dig up documentation, but I can't see that apt-cache policy outputs enough info to re-create the sources.list lines. For example: 500 http://agnes lenny/main Packages release o=Unofficial Multimedia Packages,a=testing,l=Unofficial Multimedia Packages,c=main origin agnes 500 http://agnes lenny/main Packages release o=Debian,a=testing,l=Debian,c=main origin agnes Those two stanzas correspond to two different sources.list lines. I don't see enough information there to re-create them: deb http://agnes/debian lenny main contrib non-free deb http://agnes/debian-multimedia/ lenny main ) could be wrong, of course: there are many details of apt I do not know. > debootstrap: > uses ftp.debian.org as default mirror. If ftp.debian.org doesn't contain all architectures, then that's a bad default, imho. > Probably difficult parts: > handling CD-ROM installation I don't think running pbuilder against CD-ROMs is a workable solution in the modern world. There's way too many CDs involved. Anyone who really wants to do that can be expected to go through the small amount of pain of configuring pbuilder manually. > mixed stable-backports / security / s-p-u / ubuntu / whatever > installation. The host system should, of course, be able to run such a mix freely. The environment built by pbuilder, piuparts, or other tools, should not, unless explicitly configured to do so, because the risk of contaminating uploads to Debian is too great. > I'm inclined to add a default configuration which uses the first > usable line starting with 'deb http://' from /etc/apt/sources.list, > and maybe check with a debconf question. I don't think using debconf is a good idea. Any answer you get is valid when the package is installed, but won't be valid later. The answer should be generated dynamically, each time pbuilder (or piuparts or whatever) needs it. I propose that it be encoded into a new command, apt-default-sources.list or something like that, which, when run, outputs a sources.list that tools like pbuilder and piuparts can use. Put the heuristics into that command, and then it doesn't need to be duplicated in every package that needs it. -- The most difficult thing in programming is to be simple and straightforward. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
