Well, gnome-codec-install is apt-specific, but it should be relatively
easy to adapt it or use some other similar program (not codeina).
I'll try to look at it when I can.
What is left is to figure out how would this specifically work then:
- Tainted by default, yes/no?
- Option in the installer, yes/no?
- How should the codec installer tool handle tainted-disabled case:
a) Can install the codec from the disabled repo (with a warning)
b) Asks the user if tainted should be enabled
c) Error out, asking the user to enable tainted
d) No handling, standard "codec not found" error
(note: a,b,c require some way for the tool to know what codecs exist
in tainted - for that we need one of:
x) search tainted repo automatically, like rpmdrake for backports
y) as (x) but ask user first ("do you want to search in foobar")
z) list of tainted codecs, e.g. in an pcitable-like
semi-automatically maintained file, or in website
)
- What is the proper way for the user to update his packages to tainted
versions - rpmdrake only considers updates from the /updates
repositories, so the user would get the fully enabled version of
package X only when an update is provided for it?
(I'm talking about GUI, "urpmi --auto-update" works in a terminal)
