The command 'debdelta-upgrade' is meant to be run between 'apt-get update' and 'apt-get upgrade'; it downloads .debdelta files and recreate the new .deb files from them; always using the *installed* old version of the .deb, and not the old .deb file itself.Is it safe - e.g. in case of localy-modified config files?
yes a.
