ldconfig is yet another. I've often thought a few new fields could be
added to the packages to support this. Something like:
(since pre commands don't make sense in this respect, we only need a
Config-Command: ldconfig, update-menus
Dpkg registers these commands only once for each package it installs, and
runs it only once when it enters (the start) of the configuration phase.
We could make a hardcoded set of programs to allow, but that would only
enforce policy. Since the real post/pre scripts can run anything anyway,
there shouldn't be any extra concern for security, so long as a proper
message is output when executing it. I also think it should remain limited
to a single command with no options.
