Hmm. My recollection is that installing things like apache, nginx,
postgresql etc etc (i.e. system daemons) does exactly that and leaves
them running. Please correct me if I'm wrong there, but I don't think we
do anything abnormal.

Oh, there's probably some bizarre dpkg incantation that can do that -
probably just "don't run the postinstall" or something, but that might
leave the package in a badly configured state. Again, do other system
daemons provide this sort of option? If so, how? We'll be more than
happy to cope whatever is the standard way of achieving this for Debian.

Hmm, that suggests that we should probably have the user configurable
via debconf, and then you can probably pre-seed the answers there. What
do you reckon?
