Bug#772522: live-build 4.0.3-1 does not install casper in ubuntu mode

["Rui Miguel P. Bernardo" <rui.bernardo.pt@gmail.com>]

Package: live-build
Version: 4.0.3-1
Severity: normal

Dear Maintainer,

    * What led up to the situation?

I wanted to build a live image based on Ubuntu 14.10 utopic using
latest live-build.

    * What exactly did you do (or not do) that was effective (or
      ineffective)?

I have created a new build tree with "lb config", copied the files from
/usr/share/doc/live-build/examples/auto/* to auto/config and then I've
added the following to config/auto:

        #!/bin/sh

        set -e

        lb config noauto \
        --mode ubuntu \
        -d utopic \
                "${@}"

I ran "sudo lb clean", recreated the configuration with "lb config" to
apply the new settings added in auto/config and finally a ran "sudo lb
build".

    * What was the outcome of this action?

The live image build failed with:

        [2014-12-08 03:19:45] lb chroot_install-packages install
        P: Begin installing packages (install pass)...

    * What outcome did you expect instead?

I expected that a live image of ubuntu utopic was built.

After digging what the problem was I've found that the following two
commits do not consider ubuntu mode, only debian and wheezy/jessie,
breaking the whole ubuntu mode of live-build:

        http://live.debian.net/gitweb/?p=live-build.git;a=commitdiff;h=d1eae015774db9e11ddb656ad8bc377c565f503a

        http://live.debian.net/gitweb/?p=live-build.git;a=commitdiff;h=8eaba8ea5ced274ceb8357a64ead3ff05854e9bc

I know that ubuntu mode support not a priority ATM but I was testing
live-build 4.0.3-1 with ubuntu mode and the this issue came up.

To workaround the problem I've simply edited manually the file
/usr/lib/live/build/config. I have replaced the content of
config/package-lists/live.list.chroot file with

        casper

instead of "live-boot live-config live-config-systemd".

Then I clean up the build tree, ran "lb config" again and run "sudo lb
build" to build the live image, which was then completed and booted
successfully.

I would provide a patch but I really don't know if you guys want to
deal with the content of config/package-lists/live.list.chroot using
just $LB_PARENT_DISTRIBUTION or using $LB_MODE and/or also
$LB_INITRAMFS or any other solution you may already have.

Thank you.
