That's right, asking questions interactively doesn't scale to multiple
machine installs. The query service solves this (and my proposal to
divide the install process into an interactive and a non-interactive
part doesn't interfere), but answering the questions of the install
scripts is the easy part of the game.
Some random thoughts about scaling:
There are a lot of packages with config files that can't be generated
using some simple questions (on my systems packages like autofs,
samba, lprng, X11, apt, dosemu, svgatextmode, netstd, pcmcia-cs, sane,
samba, sudo, tetex, wine). This would have to be solved too if you
want it to scale. If you want upgrades to scale, you have also to
answer the old/new-configfile question by the query service (and the
answer is only valid for one upgrade, for the next upgrade the choice
might be different), and there must be a possibility to supply the
merged configfile.
When the machines have a similar but not identical configuration, for
example hardware differences, answers must be supplied from a general,
and a machine-specific database.
