Removing kits, in Sid

I am not exactly sure why I write this... but there might be two main reasons - I wasted enormous amount of time (80% of this googling crap) and need to get at least some kind of visible outcome. And secondly - it might be of help to someone as of 'how not to get results'.

The idea was to see if I can get rid of *kits in my Debian Sid. And possibly of PAM too. This last one I left aside pretty fast - too many unavoidable deps.
What consolekit and policykit do and why they are also shitty and unneeded part in single-user desktop, that can everyone google themselves.

In my Debian Sid I got such deps for kits: they and their libraries, and Lightdm. That was all, and life seemed rosy.

1. I removed lightdm and replaced it with slim (has optional consolekit dependency) from Debian repo.
As a by-thought - Slims' login-screen looks, frankly, like shit... But slim is real light-weight and easy to configure: /etc/slim.conf and themes reside in /usr/share/slim/themes. Graphical part of themes are quite extensive - and not so trivial to change. If pointed to correct folder, slim lists all your sessions automatically.
But never mind that - of course the debian slim had been compiled with consolekit support.

2. Recompiling slim with -DUSE_CONSOLEKIT=no. My installation needed additionally libpam0g-dev for that.
After playing around with original source - I even got it 'made' (after endless tries and some conf and parameter changes) - I decided for making proper debian package.
So I played several evenings with pbuilder and cowbuilder (there are tons of material to read, some heavy packages to install and not very simple conf to conf). I managed to create quite an impressive mess - and finally went for simpler way and used dpkg-buildpackage.
In very concise way, whole thing was like that:
apt-get source slim   # downloads source packages to current folder and unpacks tars in correct way.
-DUSE_CONSOLEKIT=no  - change it in /slim-unpacked-source/debian/rules
change conf in /debian/patches/slim-conf.patch to reflect your situation (less to do afterwards)
dpkg-buildpackage -rfakeroot -uc -b  # in source folder
and there should be new slim.x.x.deb in sources root.

3. Removing vanilla slim and *kits.
Went to console, killed slim and X, then removed slim, policykit, consolekit and deps. Installed:
dpkg -i slim...new-one.deb
Rebooted.
X did not start and dbus did not start (despite I had the second one in .xinitrc).
Manual dbus-launch worked but then X claimed to have a segmentation fault. Bugger!
I reinstalled consolekit - and X started without any problems... Double bugger!
To cut it short, after trying several things - to (unsuccessfully) root out consolekits' leftovers, I threw a towel.
Shame-facedly, I reinstalled both kits. That's that - a defeat.

At the same time - there are cases of successful removals. So, it can be done. I suspect that without display manager (but I wanted to keep it), linux-with-no-kits is possible.
