That's indeed a problem I've not thought about yet. I see that NixOS
is a complex distro and I see that we are short in man power, so I
guess my proposal does not fit that well.

My point on this part was not that nothing breaks, but that no new
packages break. Or at least no trivial new packages. For example, I
just packaged "ctodo", which is almost dependency-less. These kind of
stuff really should not break and I guess it is fairly secure to (kind
of) "out source" that from github, as it generates noise in the repo.

Again, this was not the point. The point was that nothing _new_
breaks. Beeing imperfect is not desired (of course it would be ideal),
but getting better is desired. That's a small but important
difference, I think.
Mit freundlichen Grüßen,
Proudly sent with mutt.
Happily signed with gnupg.
