Hi,
Is there a guide on how to build a downstream kernel in obs like a
upstream genuine kernel?
I have a CHIP allwinner R8 with debian but I would like to use opensuse
instead.
I found a link in the wiki to a script which is supposed to help with
this (http://users.suse.com/~dmueller/contrib_kernel.sh) but like is
dead to me.
Hm, looks like users.suse.com does not want to talk to anyone outside of
the SUSE network. Hooray.
Either way, here's the script. You may need to adapt it a bit, as it's
been a while since I last used it. But overall it should still do what
you expect.
