well, this should be a simple question with a simple answer, but after mucho research guess that is not the case.
as most do, i have not only changed from the default (in my case netbook remix) package list (for instance removing most games and adding some useful apps....), but i have also made various config changes (such as the hack to disable the touchpad when keying). now on 8.04 but want to get to 9.10 (don't i?).
so seem to be two paths to do this. one is to do 4(!) updates 8.04->8.10->9.04-.9.10. ugg, seems like a risky and time consuming path. also, i have poulsboro drivers to bring along.
so maybe better to do a fresh install. in that case, what i'd like to do is to create a fresh 9.10 system on a usb device, apply all of my changes to that stick (packages, configs, ...), try it out for bit, and then bring all of that back onto my hard drive as my standard boot. isn't this what 99% of end users would want?
so i am able to create the 9.10 usb install and bring over my package list (mostly), but what about the configs and other files that are in various system folders? how do i get those to the new system? right, i don't have a list of those changes made over the past year.... and then, once happy with the new system, how to get it back to my hard drive.
am i right that this procedure doesn't exist? i hear linux guys talk about doing something like this, but don't find the tools or clear instructions anywhere.
