Actually, I don't know what to do with this PR because it is still in alpha and nobody wants to maintain it:/
@samueldr @vcunat As release managers, what do you think?

But I really appreciate your sharing, which could be useful for others, including myself:)
@tilpner Are you playing with rootless containers?

I packaged the alpha version because the changelog said Fix CVE-2019-6778 (rootless-containers/slirp4netns#67), and I figured it might not be a problem to init a package to an alpha version, because nobody was already depending on it. It would be different if people were already using slirp4netns, but this can't break anything because nobody will upgrade to it.

Yes, I was using rootless podman for an experiment, but I no longer need it.

Edit: 0.2.1 fixes that vulnerability too, so that would be okay too

Hmm, I'm afraid I don't have a solution for this meta-question. Actually, I already have at least one nix expression for a package lying somewhere that seems to work OK but I ended up not using the package in the end and I haven't "published" the expression anywhere.

Advantages (of merging)

• it shouldn't break anything
• they would make it easier for people to try the package and start using it, as not everyone can just write such an expression within a couple minutes

Disadvantages (of merging)

• it would probably just rot in nixpkgs
• not much indication in nixpkgs how much a package is maintained

I don't know... it reminds me of our usage meta.broken a little, but that's different: an intermediate state for rotting/unmaintained packages between breakage and removal from nixpkgs.

I too have a private derivation of slirp4netns :) It looks like this + enableParallelBuilding = true;.
Please add me as the maintainer. I'm ok with 0.3.0-alpha.2.
I'd slightly prefer for it to be in tools/networking rather than in applications/virtualization.

Moved, parallel building enabled, @orivej added as maintainer. Merge when ready :)

Thank you!

@orivej Could you open PR for adding NixOS pkg to slirp4netns README?
https://github.com/rootless-containers/slirp4netns/blob/master/README.md#install-from-binary

OK, but we should wait until it reaches the nixpkgs-unstable channel.
