Hallo.

I have a package libgda, which contains many database plugins.

What to do with plugin packages, which provide a xxx support for libgda.

Suppose I will do:

Package:  libgda-mysql
Enhances: libgda

Package:  libgda-postgres
Enhances: libgda

This will probably cause, that beginner will click OK for all and
package manager will install all available databases as
hard-dependencies of all these plugins.

But I want to suggest here: "Yes, libgda-mysql enhances libgda, but if
you don't have mysql installed, you probably have no usage for it." Once
in future, if user installs mysql package, libgda-mysql should be
suggested.

What I really need, is probably:
Enhances: ( libgda + mysql )


One of suggestions says, do not offer or warn about enhancement packages
with a lot of unresolved dependencies. But it is not a solution.

For example I have also:

Package:  gstreamer-plugins-extra
Enhances: gstreamer

The package also has many unresolved dependencies, but I really want to
suggest here: "Yes, install all these dependencies to have a cool
gstreamer package."


Is such feature possible or planned or what is the syntax?


And additional ideas:

Is it possible to use Enhances for virtuals or Suggests for symbols
instead of package name? I want to say: "Yes gimp-help enhances both
gimp and gimp-unstable."

Package:  gimp-help
Enhances: gimp-2.0

Package:  gimp
Provides: gimp-2.0

Package:  gimp-unstable
Provides: gimp-2.0

Another use:

Package:  plugger
Suggests: mp3_player
(where mp3_player will be virtual provided by all MP3 players)


Maybe it should be evident, why package Suggests/Enhances other package,
to provide enough information to user. For example:

Package:  mc
Suggests: (xv eog gv pdftotext)("To provide default viewers. You can define different viewers and ignore these suggestions.")

Package:  gnome-session
Suggests: gnome2-user-docs("To provide enhanced user documentation.")
