pbuilder-apt-config

[Loïc Minier]

 Trying to address your concerns with the builtin map not being data
 driven, I looked at the code again and realized there's a case which
 makes this relatively hard: PPAs.  Currently, the code of
 builtin_mirror_map() has:
[...]
      debian)
        echo "http://ftp.us.debian.org/debian/"
      ;;
      debian-archive)
        echo "http://archive.debian.org/debian/"
      ;;
      ppa:*)
        people_ppa="${archive#ppa:}"
        case "$people_ppa" in
          */*)
            :
          ;;
          *)
            people_ppa="$people_ppa/ppa"
        esac
        echo "http://ppa.launchpad.net/$people_ppa/ubuntu/"
      ;;
[...]

 I could move all configs except ppa:* to a map variable, something
 like:
builtin_map="
backports.org           http://www.backports.org/backports.org/
debian                  http://ftp.us.debian.org/debian/
debian-archive          http://archive.debian.org/debian/
"
 that would make it easy to dump the map, but I would have to special
 case PPAs.  :-/
