I think I understand your workflow and your need. However, I
unfortunately don't think your proposal works properly: the next time
you will do "make clean", the build directory of your package will have
disappeared, so Buildroot won't know that it should do a "git pull",
and will use again the pkgname-HEAD.tar.gz file from the dl directory.
Or maybe I misunderstood your proposal ?

In your case, wouldn't it be better to not let Buildroot download your
custom applications from Git, but rather give Buildroot the path to a
directory where you have the source of code of the applications ? This
way, you can handle this directory however you want in terms of
revision control: Buildroot will never remove it.

What do you think of the proposal I've sent on May, 18th ? See
http://lists.busybox.net/pipermail/buildroot/2011-May/043320.html.

Thanks for your suggestion!
