Well, it's quite clear to me: dpkg simply doesn't order the installation
sequence, you have to use a higher level tool like apt or aptitude for that.
You can try the following:
Drop the deb files in a folder, say /home/foo/debs, then run
dpkg-scanpackages /home/foo/debs /dev/null | gzip > \
/home/foo/debs/Packages.gz

Add to /etc/apt/sources.list:
deb file:///home/foo/debs ./

and run apt-get update && apt-get upgrade. This should work flawlessly
(tested it myself).
I did this for your proposed patch and stored the files on my server.
You can test them by adding

deb http://debs.michaelbiebl.de/upstart binary/
deb-src http://debs.michaelbiebl.de/upstart source/

to you /etc/apt/sources.list file.

@madduck: The repository also contains upstart 0.2.5 packages.
Applied is the patch for glibc-2.3. I addition dropped the dependency on
linux-kernel-headers and glibc from experimental and changed the
dependency on sysvutils -> sysvinit-utils, as this is what pere chose as
name for the split package. Give them a try.


@hmh: The sysvinit package still has the Essential tag. This makes it a
bit cumbersome if you want to install a replacement init system like
upstart, initng or runit-run. Would it make sense to drop the Essential
tag from sysvinit and let all init systems have a "Provides:
init-system". We could then introduce an new essential package which
would depend on "init-system | sysvinit".
If we later decide to switch to a new init system, it would be much easier.

Cheers,
Michael
