If I understand well you are proposing to add to dpkg a mechanism to
have a delayed installation/configuration, unless the package able to
do it will be available?
It seems great to me.
I was looking for something similar to handle the installation of
manpages:
now Debian has manpages in five languages, and an ever growing number
of packages comes from upstream bundled with docs in different
languages.
The purpose to install only the docs in the language required
conflicts with a different need that can raise later.
This mechanism can handle the situation:
each pachage that has manpages in different languages will install
only the manpages in the languages "active" (for example listed in
/etc/lang, or /etc/defaults/<something>), and add its name to a file
under /var/lib/dpkg/man/<lang> (one file per language) to let the
system knows of the existence of these other pages (generally one
or few per package, too little to put in a separate package).
The postinst of this package should accept a new parameter
(e.g.: install_man <lang>) and install the manpages in the language
requested when invoked in such a way.
A special package <lang> can be installed to create the hierarchies
requested (under /usr/man, /var/catman, etc.) AND to execute the
postinst of each package listed in the file /var/lib/dpkg/man/<lang>.
But where are the manpages that wasn't installed?
Gone.
Should we need to duplicate all the manpages in other languages
to put them ALSO in the special package <lang> to be installed
later than the package they belong to? (Now is happening a strange
thing: after installation of manpages-it, you can have the manpage of
a command that is not available because the package is not installed.
Or even worse, in case of manpages for conflicting commands with the
same name ... )
Any comments?
ciao,
Fabrizio
