 possible to strip debian back to base system?

Is it possible to strip debian back to the base system using apt or dpkg?
to remove all programs and libs back to that point?
When I install debian i just install the base system, then I add what I want from there.
Then I get to playing with things, trying to learn how stuff works.
Sometimes I trash my system beyond repair, or at least that i have the patience to repair.
Curiosity killed the OS
maybe I should just install the base on a seperate partition and copy that over when i destroy the other one?
thanks

well if you really mess stuff up, just deleting packages isn't going to help you; You'd most likely want to wipe and reinstall(this is where keeping /home on a separate partition comes in handy, so you don't need to wipe that one) Though, its pretty tough to totally trash a system to this point... What have you done before that made you think the system was trashed?
You could probably easily write a script to dpkg --purge all packages below a certain priority threshold. The easiest way would be, after you reinstall, do dpkg --get-selections > somefile, and save that file. Then to restore, you can just do dpkg --set-selections < somefile.

You can do it but you might break apt. If you were using Gentoo I would say go for it.

Please explain what you mean by "break apt" as well as why "using Gentoo [you] would say go for it"?.. Well, don't really, it would be pointless.

Sure, you could geting a list of all the packages in base, then remove every package on your box apart from those ones (even with awk or whatever, it's going to be a hassle)... Or you could just reinstall, which:

If it's literally trashed beyond repair (uh, what the hell is wrong with it - I mean specifically?) then reinstall is your only option. Were you on woody and failed an upgrade to sarge or something? Or running unstable and pulled some funky package from experimental?

im good at using rm or cp at inappropriate moments  
and i like to install alot of different packages to see if i like them.
so sometimes i end up with grips of libs and other packages that i dont
need when i remove a package, that i don't want.
lately i have been doing this when i install something
#apt-get install *package > install_list.txt
just to keep a list of what gets installed.
the only problem is apt-get wont let me remove all the packages at once. I have to feed it a few at a time. like this
#apt-get remove *package1 *package2 *package3
#apt-get remove *package4 *package5 *package6

That's where scripting comes in handy.

I have broken the debian package manager many times trying similar stuff. Remove one program no prob....strip it down and you cause problems. I did this once and it removed apt even though I did not tell it to. Portage is much more resiliant. For the record I like Debian, but you just have to be more cautious. Gentoo is a bitch to get installed, but it is more robust.
