Bug Description

Binary package hint: debian-installer

I tried to make a custom jaunty alternate ISO today, following instructions at https://help.ubuntu.com/community/InstallCDCustomization . The ISO I made works, except that it fails to get networking up automatically. Colin Watson, a debian-installer maintainer in Ubuntu, looked at it and concluded that there is some undefined behavior in d-i that gets masked away by netcfg coming before ppp-udeb in the official Packages file. My custom ISO has an unsorted Packages file, resulting in brokenness.

From IRC:

<cjwatson> liw: sort your Packages file lexicographically by package name and it'll work ...
<cjwatson> liw: unfortunately there's a bit of undefined behaviour in d-i that's currently resolved by "netcfg" < "ppp-udeb" :-(
<cjwatson> liw: (this is a bug, obviously! please file it)

  drop ppp-udeb from installer to supported-installer, since it isn't used by default and causes confusion when customising images (LP: #362989)

I'm leaving this bug open on anna, since I'd still like to get the ordering problem fixed.

Does that mean that ppp-udeb was completely removed from the image? Installing via pppoe does not work in 9.04 regardless whether the Packages file is sorted or not. It has worked fine in 9.04-beta. A quick check reveals that ppp-udeb is no longer included in 9.04, while it _was_ included in 9.04-beta.

Are you having plans to put it back into the image again in 9.10?

Is it possible to include it into 9.04 by pulling from "supported-installer" somehow? Any pointers how to do that?

ppp-udeb is missing in 9.10, too. Any chances to get it back in the installer?
