Hi,
I am trying to figure out how complicated it'd be to add the sound subsystem to the list of supported packages - there are many cases where I only want the latest and greatest sound drivers and nothing else beyond the minimal dependencies. Bear with me if I am asking silly questions, I am not familiar at all with the backports environment and only tried to progress from the wiki and code.
question1: is there a way the list of packages can be selected? I'd like to use the backports infrastructure only for what I care about (media, usb, audio). It'd be really nice if I could limit the updates to the parts I care about (media, usb, sound) and remove all the networking part I don't really have a use for. It's fine if the releases include everything, I only want to limit the changes in my own workspace.
question2: I am not sure I understand how the code is generated. Nothing seems to work/compile even without my changes... If I use linux-next with the next-20150731 tag and the latest backport code, I get:
~/backports$ ./gentree.py --clean --verbose --gitdebug --git-revision v4.1.6 ../linux-next ../linux-next-backport

Now if I use branch origin/linux-4.1.y, the tree is generated but usually doesn't compile (random options selected)
Can anyone help with a known config that works?
question 3: how exactly does ckmake work and what am I missing?
:~/backports$ ./devel/ckmake
[snip] backports/Makefile does not exist
Thanks,
-Pierre
