Re: Packaging Problem (Is preinst really pre?)

Why are you splitting up the package if they cannot be installed
separately? Such splits only make sense if the amount of data the
package needs warrants a separate arch-all package.

See the Debconf manual about this: If you have shared configuration
items, put the templates into all of the packages and ask for the
configuration values in all config scripts. Only the first one will
actually show the questions, it will be skipped when the other packages
configure. The postinst should never ask any questions at all.

Yes, because the preinst isn't even extracted at that point. All
packages that are going to be installed are configured either before any
of them is unpacked (if apt-utils is installed) or during postinst time
(if apt-utils is not installed). I believe it is also legal at any other
time in between (e.g. while the package is being unpacked in the
background).
