If you wanted this to use PyPy instead, you would use the name of the PyPy derivation here instead - eg "pypy3".
If you want to try this, I suggest using a very recent version of nixpkgs master@HEAD (or waiting for the 23.05 release). I don't know if wormhole will have issues or not but I wasn't able to get Tahoe-LAFS to work on PyPy without a lot of hacking, even on the NixOS 22.11 release branch, due to a lot of Python package incompatibilities with PyPy that hadn't yet been addressed. But after 22.11 it looks like someone has paid a bit closer attention to PyPy support and it's a little easier.

Thank you for the tip.
If we want to compare Debian vs NixOS images, PyPy would help indeed.
But I'm not sure how much time it will take (time was also an important factor).

Might want to consider using a tool like npins or niv here, it will also make updating the pin much more pleasant

I was looking into niv, but I could not see how/if it is used for PrivateStorageio!
(I've just made a copy/paste :-)

@exarkun : how do we update nixpkgs in PrivateStorageio?
There was a problem hiding this comment.
The shell script ci-tools/update-nixpkgs calls, in its function update_nixpkgs on line 160, update-nixpkgs defined in tools/default.nix line 17 via shell.nix line 6. That in turn calls the python script tools/update-nixpkgs to update nixpkgs.json.
The python script already broke once because the HTTP library it uses changed its API and we didn't have its version pinned.
That's why the moment @exarkun turns his back I'll replace the whole thing by my 12 line update-nixpkgs.sh shell script I have still sitting in my working directory which just creates a new JSON from a heredoc hr hr hr

Thank you @hacklschorsch.
I was surprised there is not some nix command to do this...
And I was already trying to implement this in bash. :-)
I guess I'll not go further here.

FWIW I think there are nix commands built-in when using flakes …

I did not dare pushing this experiment to the flake level :-)
Nice to know this could help to simplify the update of the nixpkgs.
I'll see later if I can spend some extra time to improve this (with npins, niv or flake).
Maybe interesting case for a "Nix Intro" session?

I won't be there this week because national holiday, but next week I could talk a bit about these

No business value in adding yet another way to update one three line json file.

Refers to #35
This pull request is merely an attempt to use Nix to build our Docker images, so we can explore the pros and cons before possibly consuming them downstream.
