Comment 10 for bug 66615

As a temporary workaround reference for me(when I install this again after a while forgetting eveything that I had to read up to fix the problem) as well as others, here are the steps.

Steps to be taken after the installer fails.

1. sudo touch /etc/inittab
2. sudo dpkg -i /tmp/daemontools/admin/daemontools_xxxx.deb
3. (Add the config mentioned by mrts to /etc/event.d/svscan)
    sudo pico /etc/event.d/svscan
    add this>>
                      start on runlevel 2
                      start on runlevel 3
                      start on runlevel 4
                      start on runlevel 5

                      stop on runlevel 0
                      stop on runlevel 1
                      stop on runlevel 6

                      respawn
                      exec /usr/bin/svscanboot
     <<
4. sudo initctl start svscan

From next boot onwards, you don't need to do (4).
