debconf with locally derived options

[Richard Hector <richard@walnut.gen.nz>]

Hi all,

Is it possible for debconf, in the config file, to ask questions to
which the answer is one of several that make sense on the local system,
but couldn't be put in the templates file?

One example would be configuring a daemon, and asking which of the
configured IP addresses of the machine it should listen on. Obviously
the packager has no idea what IP addresses are going to be on the target
machine, so can't list them in templates. I would therefore want to
generate the list on the fly, and present them as options to the user.

Thanks,

Richard
