** Summary changed:
- fails to consider Provides when promoting packages from lesser seeds
+ needs to try promoting alternatives before adding new packages to output
** Description changed:
- Binary package hint: germinate
-
Cody Somerville noticed that usplash-theme-ubuntu was being pulled into
the Xubuntu desktop task (and indeed all flavours' desktop tasks),
despite other usplash themes being seeded. I think this is because
usplash is in the desktop-common seed now. Normally germinate promotes
packages from "lesser" seeds (for this purpose, desktop is a lesser seed
relative to desktop-common because it inherits from it) in preference to
finding one for itself; however this doesn't work in this case because
- the dependency relation from usplash is on the usplash-theme virtual
- package and germinate doesn't consider this. It needs to.
+ the dependency relation from usplash is "Recommends: usplash-theme-
+ ubuntu | usplash-theme", and germinate doesn't try promoting each of the
+ alternatives (which would lead it to usplash-theme provided by xubuntu-
+ artwork-usplash) before adding new packages (usplash-theme-ubuntu) to
+ the output.
+
+ This needs to be handled delicately, as we can only promote packages
+ from "close-by" seeds this way. If you try to do it across the board,
+ you end up with debconf-english getting promoted all the way from
+ supported-development up to required! Seeding debconf-i18n in required
+ would work around this but is far too big a hammer; it's better to make
+ germinate be more subtle. I opted for promoting non-preferred
+ alternatives only if they're in a seed that's generating the same task
+ (which is the relationship desktop has to desktop-common).
