We use quilt to manage (push/pop) patches. We could use
QUILT_PATCHES=<dir where patches are found> in .quiltrc file.One
problem I see is that sometimes we use patches  from more than one
location. Sometimes we develop patches on top and how do we decide
where this patch is put if we have more
than one locations for the patches.
