If you want more eyes AND more backporting, how about you move ahead to the newer version instead? In the end, if you'll backport most of the code you end up with close to the same code base. Doing security and minimal security fixes on -stable is a very different endeavor than creating downstream trees full of feature backports. (We only care about a few features, you might say -- but once you join up with others, who care about a few but different features, you'll eventually end up approximating the kernel from which you're backporting all these features). -Olof --001a114a958c05f4ef053789d402 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable

Like LTSI already does today?=C2=A0 :)

 It looks we share some basic ideas on backporting part. But industry need m= uch more backporting features. and new features which out of upstream aren&= #39;t started from here, since it's a upstream quality without more eye= s in community.

If you want more eyes AND more backporting, how about you= move ahead to the newer version instead? In the end, if you'll backpor= t most of the code you end up with close to the same code base.

Doing security an= d minimal security fixes on -stable is a very different endeavor than creat= ing downstream trees full of feature backports.

(We only care about a few feature= s, you might say -- but once you join up with others, who care about a few = but different features, you'll eventually end up approximating the kern= el from which you're backporting all these features).
