You want to wipe the root partition? Don't, you'll brick your device. Just re-flash and be done with it.

open xterm and type:
rm -r /home/user/.*
and press enter. Say bye bye to your contacts, calendar entries, application settings, configs and so forth.
Thanks again, trying to figure out how Maemo organizes things for future reference.

Everything related to you as a user should be in /home/user (and any settings you add to a program, like downloading saved remotes), remotes that came with the might be there, in /opt or elsewhere but if they came with the app then they should be uninstalled together with it as well.
Note that I don't know how Irreco works, so I included both possibilities. Running dpkg --contents on the irreco package should show whether they came with it or not, or you might know whether you downloaded them or not.

Is it safe to do rm /home/user/* and rm /opt/* and then flash the firmware again and finally be at the true out of box state?

http://wiki.debian.org/FilesystemHierarchyStandard
In Ubuntu, nothing is put in /opt by default. That's where I put packages that are not in the official repositories.
I suspect that on a fresh N900 /opt is empty -- I do not have my N900 handy, so I can't check right now.
FYI, under home, "user" is your username, not the word "user" on a normal Linux system. On the N900, I have never looked...
And I suspect the experts here will tell you that the best way to "finally be at the true out of box state" is to erase the root partition...
However, I should point out one other thing. Maemo doesn't have a registry like Windows. Even if some stuff from uninstalled apps is left behind, the chances of it having any effect on the operating system whatsoever after you reflash are slim to none. For testing, I cannot imagine that these remnants would be of any concern after you reflash. To my knowledge, Linux doesn't work that way. Problems like that are more of a Windows thing.
If your concern is privacy, then wiping the memory might be what you need. But I think your earlier post said testing was your objective.

Google for gconf.
It's just as opaque and mysterious as the Windows registry too.
Note: I'm assuming, because Gnome uses gconf and Maemo 5 uses parts of Gnome. Don't have a device to check yet.

gconf is for user preferences, afaik. In my experience, Linux does not have registry problems like Windows. And, at least on my desktop, my gconf stuff is stored under my home directory.
EDIT: sorry, I wish I knew more about exactly how the N900 was set up. I realize the general Linux discussion is getting off topic. I'll let others carry forward who can speak specifically to the N900.

I've only been using and developing Linux every day since 1994, on all of my primary machines for work (even for Windows and DOS development I've tended to cross-compile from a Linux environment) and personal use, oh, and did I mention the servers
Yes, I run Linux.
The "registry" problem is getting slowly worse, imho. A lot (but still a minority) of things that used to be in documented config files in /etc or $HOME are slowly creeping their way into undocumented structured config files here and there.
On a modern Linux desktop, with wireless networks configured using NetworkManager, where are the profiles for each access point stored? That's not really "user preferences". I can't tell where they are because there are multiple old sets of access point info buried in the .gconf directory, from older versions of the software. Sounds like "registry cleaner" territory to me...
gconf is for user preferences, afaik. In my experience, Linux does not have registry problems like Windows. And, at least on my desktop, my gconf stuff is stored under my home directory.
It's not just the .gconf directory on a full Linux desktop. See also .gconfd, .gnome2, .gnome2_private, .gvfs, etc.
But you're right, "rm -rf $HOME/.??* $HOME/*" should sort it out

Lets not fight gentlemen lol
Since you both seem to know a lot about Linux in general.
Can you tell me what directories to wipe to get everything that the N900 didnt come with off?
I was reading that heirarchy you linked and that helps ALOT thanks! But curious what files you guys think would do it, and what the terminal command would be?
Im assuming rm /home/* and then rm /opt/* or will that kill the device?
Thanks again!
