The dpkg --get-selections/--set-selections is a great way to save the energy that you've spent. Yet it is not enough. Go to the List-Archive http://lists.debian.org/debian-user/ and follow the recent thread of "Configuration DB", if you want to save more of your energy.

True.

Yep, thanks for the correction. Looks like I should have done "man apt-get" in addition to recommending "man dpkg". :-) > > (man dpkg for more information.)

"dpkg --get-selections >& /file/to/output.txt" "cat /file/to/output.txt | dpkg --set-selections" "apt-get upgrade" (man dpkg for more information.)

Run the command "dpkg --get-selections > ~/selectionfile".

Piped package list
I seem to recall seeing once that one of the package tools (dpkg, apt, or another, I don't remember) could save a package list that could later be piped as input to return a system to an identical list of packages with one command. Am I crazy, and if not, how is this done? TIA, Aaron __ Do you Yahoo!? Yahoo!
