[Buildroot] Best-Practice Suggestions for developing package patches in buildroot

Please read Section 8.6.11 "Using Buildroot during development"
(http://nightly.buildroot.org/manual.html#_advanced_usage). It will
give you a good idea, how to work on upstream code.
<pkg1>_OVERRIDE_SRCDIR is the keyword.

_______________________________________________

To develop a little bit on that, we are in the case of
* a package that is already part of buildroot
* to whom you want to develop a new patch (not apply an existing one)

I usually do a git clone of the package at whatever version BR uses
then use OVERRIDE_SRCDIR to force BR to use my clone as source.
I modify the source that way, using the power of git to modify
the sources locally and save different patches into a chain of commits
once I'm done I use git format-patch to do a patch serie that I can
add to buildroot/upstream

I keep my git clone around because it makes respinning the patches much
easier than if I had to work directly with the patches themselves.

I used quilt a long time ago, but now that I understand git rebase -i
it's much more handy than quilt...
