This question comes to my mind every time a developer decides to
drop/add a USE flag to ebuilds like gcc/webkit-gtk/libreoffice...
I think that we should have a file (like used for category movements) to
let PM know how to handle this situation.
For example,
category/foo-1.0 has a "gnome" USE flag but, later, that one is dropped:
-> If it is now *enabling* that support always, our file could have
something like:
category/foo gnome + -> that would mean that, when "gnome" USE flag is
NOT found, portage assumes it as being enabled, that will mean that
people having previously "gnome" enabled wouldn't need to rebuild the
package
... and the opposite
What do you think?
Thanks

We could do something like that. You should propose it in the gentoo-pms
list.

OK, wanted to be sure a similar idea wasn't rejected before :)

I recall Brian Harring proposing something like that in the past, but it
never materialized.

I once half-implemented something like this but never got to finish it,
I'll try to dig up my code and check out its state.
I recall using updates/ to tell portage what happened, which then updated
the VDB to reflect the new state.

I have opened this same thread in pms-list, if you are able to forward
that code there, would be highly appreciated :)
