Thanks for your explanation, Jaret.

Yes. I get the point that it is better to maintain the sources on the
local development platform, as we have better control over the sources.
That is actually more and more applicable these days, in the case of the
"contaminated packages" (which is quite a lot recently and will be more
in the future). So that we can cherry-pick only the un-contaminated and
necessary changes.

In the case of eudev, I believe I can still trust the people who
maintain it so far, though I needed to add a patch to remove the
"contaminated" changes. I think it is still reasonably maintainable
without having the copy of the source. But that is because I have only
been observing it in the last few days. So let's see about that in
longer term.

As I previously mentioned, there is no release tag on the master branch.
The latest release tag on eudev, i.e. v3.0, that you are referring is
146 commits behind the master branch. I decided not to include the
debian build package script for release tag v3.0 as it has some issues
that I experienced myself. All the issues that I experienced have been
fixed by the commits after release tag v3.0.

Yes. I did fork your eudev project on gitlab about 3 days ago. But I
noticed that I would have to pull and push a lot of commits as the
source in your eudev project is 491 commits behind the gentoo/eudev
master branch. So I dropped it as I will need more time to learn a lot
more to be able to properly do that. So I decided to fork only the
debian directory from your eudev project and only up to a certain commit.
