I believe this not to be a good idea. When you do this you mess around with
config files under the control of dpkg. With all the mess that creates.
I would reinstall everything you had/need again and then diff prior to mass
overwriting the files.
dirdif ()
{
\diff -qrB --exclude='.hg' --exclude='.git' "${1%/}" "${2%/}"
}
[
'/var/lib/apt/extended_states' has the complete package list and knows which
packages are autoinstalled and which have been installed manually.
If you don't mind i attach my own '/etc/cron.daily/etckeeper' (it is only 4k)
which takes care for me to commit those important data into hg.
You can modify it to use your referred vcs instead.
It also compiles a list of installed packages into '/etc/apt/backup/'. Look at
the top of it.
Hope this is useful to you.
