Wow, this is a seriously sweet post. You have a spare n900 right? We would'nt want you rm'ing /etc/rc*.d on a production device!

So, I've tested removing /etc/event.replace.d and /etc/rcX.d on my N900.
The results:
It boots just fine!
Feel free to try it, although if it doesn't work out I'd recommend having RescueOS loadable from U-Boot at the ready.

Re. /etc/event.replace.d/
Many system services place the upstart file in /etc/event.replace.d/, but then postinstall copies it to /etc/event.d.
I guess this is a way of ensuring that the script is only really put where upstart will find it once the whole package has been extracted.
So I officially state:
BEGIN:
You can wipe out the folder if you like.
It will never be used during booting.
The only thing that could happen is that you install some program (which comes with an upstart script), and the script is placed there.
If so, GOTO BEGIN (if you like).
Next is /etc/rc?.d. Thanks @Hurrian for confirming that the N900 boots just fine after deleting those folders. Just in case I want to figure out WHO/WHAT created those folders in the first place.

[*] OK, I suppose matchbox is started (and the theme framework setup) so that you get the familiar alarm UI if necessary.
When I have some more time I will make a post for each system service (or for a group of them) with an explanation of what it does. I guess a Wiki would be the best way, but I just can't find a way of creating an article
Add.: and more importantly, the reboot and shutdown process has to be duly documented.

. If my analysis is correct, then the device lock screen should NOT appear when in ACTDEAD mode.Would be happy in somebody would confirm this.. but, how do you turn the N900 down (or rather, go to ACTDEAD) when the device is locked?!
I have to say I very rarely code-lock the N900, and when I do, I lock it manually and unlock it a few minutes later..

I mean I have mapped ctrl + right arrow mapped to matchbox-remote --next via xbindkeys. When pressed it switches to the next application, alt-tab like
That means matchbox is used in hildon or am I totally wrong?

I've gone through the boot process of Maemo5 and made a list of all scripts that are run, starting from /sbin/preinit all the way to /etc/X11/Xsession.post/99initdone
It's just an (indented) list. I may turn that into a nice graph some day, but I don't think it's that useful.
Please note that some Nokia-preinstalled services may not be present (if I have uninstalled them), while some of the listed services may come from additional software (e.g. sshd) not part of stock-PR1.3.
There is still the question of what role (if any) /etc/event.replace.d has (have to look at upstart source code) as well as some scripts in /etc/init.d (some are used by the /etc/event.d scripts, others not) and /etc/rc*.d.
I think /etc/rc?.d is a relic from previous Maemo versions, but I have to investigate that more in-depth. If I'm reasonably convinced that this is the case, I will wipe out those folders and see if everything works OK.
Anyway, here it is (also attached to the post).
