'dpkg --get-selections' will output all selections to stdout, and 'dpkg
--set-selections' will set selections from stdin. you can use this to
redirect selections to a file and/or over a network connection with rsh
or ssh.

this isn't perfect, but can save a lot of time when you are building a lot
of identical (or nearly identical) systems.

try installing the dpkg-mountable package and selecting that as the
access method (first option on the dselect menu). dpkg-mountable is a
greatly improved install method which does what you want. it's close to
perfect.

IMO it would be perfect if it sorted the packages into dependancy order
before installing them (maybe by making use of manoj's pkg-order stuff).
