As I have now discovered in response to your raising that: deborphan also supports two ways of listing packages which should be kept: the '-e' / '-exclude=' option (see the man page), and /var/lib/deborphan/keep. The former accepts a comma-separated list of package names, passed at launch time. The latter is a file with a newline-separated list of package names. If you list all explicitly-installed packages that you want to keep in the keepfile, then it might even be useful to run deborphan with '-a' / '--all-packages', which removes the "check only libs, et cetera" section restrictions. I may have to explore that, myself. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
