I'm trying to use github to track my own portage overlay and wanted to be able to easily include & pull down changes from upstream file repos.
Thing is when I pull them down I will often only need a single file or a handful of files from the remote source repo that provided the original ebuild file I want to include in my repo.
What is the best/recommended way to track an upstream source repo but only 'in part', using git?
Example: I want to include the content inside this particular folder of a git repo into my own git repo, without including the rest of the repo.
Edit:
It doesn't make sense to include the rest of the repo since an ebuild is just install instructions so I shouldn't be cluttering up my overlay with non ebuild files. And forking my own repo, deleting all their files and constantly only merging down part of it then making that a submodule of my overlay repo seems counter productive / over complex (not to say it may not be the preferred route, I'm still not sure I fully get how these git gurus think)
