Hi, jhcha54008 <jhcha54...@free.fr> (2017-12-30): > Just to summarize what I have found about backports support in debian > installer (did I miss something important ?) : > > As you pointed out previously, it may be useful to build netboot images > of the debian installer with a newer kernel - and even some newer udebs > from backports. > > May I ask if your message : > > https://lists.debian.org/debian-kernel/2014/01/msg00371.html > > reflects the current state of the efforts to merge backports support ?
I have refreshed patch series once in a while, but never got around to merging them. > Reading your message and the thread, I see three different use cases : > 1 : kernel only : no udebs from backports but kernel modules and image. > 2 : everything from backports : udebs from backports are preferred to others > (that's what you implemented, if I understand correctly) > 3 : mixed : some udebs from backports are included, but some other not. The current idea is to pick (3). > In the second case (everything from backports), dependencies should be > satisfyied in the union of stable and backports. The question was if udebs > from backports should be unconditionnally preferred.

Is this of practical relevance ? > > At the time of writing, five udeb packages for amd64 have versions in both > stretch and stretch-backports : Implementation would look like: selecting what packages to pick from backports at d-i build time, and implement the appropriate merging from different Packages files in net-retriever, based on this “policy”. I'll try to get back to this during January, and post updated patch series/status/etc. once I've done a first pass on it.
