[Meego-kernel] About kernel-headers package in Meego (V4L2 subdev/Media Controller)

[Teemu Tuominen]

Ok, I see your point, however the derived products will have to structle with the issue anyhow. So, I would prefer a strict lining to follow the targets that will affect on userland architecture and the decisions what projects are selected into core. In some cases even if they are experimental - The Meego is. However, I'm not experienced at all in how such is handled in other distros and though ok with the flow. 

Thanks,
-Teemu

I'm not very happy about it.... you're going to get applications that
use an ABI, and if the ABI changes in the upstreaming process, suddenly
all your apps will break.

until this is accepted by Linus, we really ought to not do this.  Having
a package as mentioned is ok if Linus already took the change, but did
not make a release yet.
But these ABIs aren't nearly that far yet.
