* Resynchronise with Debian. Remaining changes: - Install language packs and language support packages. - Expand progress bar length to 1000 for better granularity. - Mark any pending update notifications as seen after installation. Requires update-notifier (>= 0.40.1) to take effect. - Move final sources.list into place before trying to install language packs. - Remove special popularity-contest handling; Ubuntu just includes it in standard. - Divert update-initramfs and call it just once at the end (with bind-mounted /dev, /proc, and /sys, and a preceding update-dev). * Update pkgsel/language-packs choices. * Use unauthenticated Vcs-Bzr URL.
