I've been fiddling with Ubuntu a lot to get it looking and working just the way I want it. Apparently half an hour ago I pushed it just a little too far and caused my PC to crash, and when it rebooted, I got an error and had to run fsck manually. A bunch of problems existed which were fixed after hitting Y about 20 times when prompted, and eventually I got everything back to normal (or so it would seem). Needless to say, I gave up with the tweak I was playing around with. I guess I should know better.

Anyway, my question is this: is there a way to back up onto a CD all of the settings and customizations that I've made to date along with Ubuntu itself? I know the OS is robust, so is it possible to be able to boot off of, say, a thumb drive and have absolutely everything working identical to my desktop if I took the drive to a friend's laptop? Obviously things like hardware drivers wouldn't work since it isn't the same machine, but I would at least have a partial backup to work with if I ever do FUBAR my installation. :/

If not, is there anything out there that could do something similar? I don't even know where to start Googling my first question, but after a while I'm sure I could figure out the last one myself. Any help is appreciated, regardless.

i'll tell you after you tell me this "tweak"

Trying to get my Hauppauge TV tuner's IR remote to work. I fucked up in terminal apparently.

that's not much of a tweak. ok, well i don't have an answer for you anyway, sorry.

Backup /etc and the .* files/directories in your home dir regularly (daily, say) and there is little you could do that would irreversibly wreck your system.
