Nix Installer WG - 2023-05-10
Last meetings' notes: https://md.darmstadt.ccc.de/KhuRgW6qRSWSZAbNlKWZBQ
- Determinate Nix Installer Check-in
- started testing auto-allocate UIDs
- Passing all the tests, merged but not yet released.
- we'll add a thing to do phased roll-outs of new versions. Especially for things like this :).
- 2.15.0 merged, but hasn't been released on our end yet.
- Wishing to have a unified to install & use Nix in a container.
- SSL / network trouble report: https://github.com/NixOS/nix/issues/8250
- Noticed the successful connections TLSv1.3, and so is the failing one.
- The cipher seems good, but I'm no expert: AEAD-CHACHA20-POLY1305-SHA256
- The connection is being aborted right away, no read succeeds.
- The network does seem unstable, even without Nix installed...
- they've tried so many times we'd think it'd have worked at least once by now with Nix installed.
- Some mysterious problems with ISPs? With mobile internet, it seems to work...
- https://github.com/NixOS/nix/issues/8250#issuecomment-1529842256
- Posted some follow-up questions:
- https://github.com/NixOS/nix/issues/8250#issuecomment-1542314751
- ... otherwise out of ideas.
- Upstreaming :elephant:
- Logistics
- Fork the installer into the NixOS org.
- https://github.com/NixOS/experimental-nix-installer
- Add Travis as a Maintainer on the repo. (done)
- Create a project on Hydra that Travis can manage.
- https://hydra.nixos.org/project/experimental-nix-installer
- Flakerefs:
- Linux (MUSL):
github:nixos/experimental-nix-installer#nix-installer-static
- MacOS:
github:nixos/experimental-nix-installer#nix-installer
- Note in the forked repo that nobody is using it, and it is the wrong place to report issues.

|  K900 joined the room. | 09:32:58 |
| K900 | Hey, I fiiled https://github.com/DeterminateSystems/nix-installer/issues/474 already but was originally going to post here | 09:33:24 |
|  Ulrik Strid joined the room. | 09:52:59 |
 hexa | wait, steam does special handling of /nix already? | 10:23:31 |
| hexa | * wait, steam does special handling of /nix? | 10:24:34 |
 Zhaofeng Li | Not Steam but SteamOS. They just added a bind-mount of /nix since the root is read-only | 10:25:31 |
| hexa | basically what I meant 😄 | 10:25:53 |
| Zhaofeng Li | Pretty surprised that they added this though. Looks like they are somewhat interested in Nix to add such a specific workaround | 10:27:35 |
| K900 | There's a lot of people on youtube recommending people use Nix to install stuff on Steam Deck | 11:43:22 |
| graham | oh cool :D | 11:57:34 |

| Ana | Meeting today | 14:00:05 |
 Matthew Kenigsberg | Théophane: could we get some decisions from the Nix team about which features need to be changed to start distributing the experimental installer? The differences are telemetry as well as what's listed here: https://github.com/NixOS/experimental-nix-installer#installation-differences | 14:41:51 |

|  raitobezarius changed their display name from raitobezarius to disko in NixOS 23.11 when. | 13:32:56 |

| graham | I posted some performance statistics from github actions: https://discourse.nixos.org/t/introducing-the-determinate-nix-installer/25848/9 | 17:31:16 |
| raitobezarius |
That introduces the use of auto-uid-allocation, and the performance impact on Linux is stunning, making 100% of installs complete in fewer than 5s:
more of this please
| 17:32:05 |
| raitobezarius | beautiful | 17:32:10 |
| graham | we only serve 0.9.0 5% of the time right now, but we're about to increase that to 20% today | 17:32:41 |
| K900 | So was the slow part just shelling out to adduser however many times? | 17:32:53 |
| graham | (I'm quite cautious about auto-uid-allocation having surprising side effects) | 17:32:56 |
| graham | well, we exec it, ... but yeah | 17:33:05 |
| graham | * well, I think we exec it, ... but yeah | 17:33:08 |
| K900 | Cool | 17:33:33 |
| raitobezarius | In reply to @graham:grahamc.com
(I'm quite cautious about auto-uid-allocation having surprising side effects) Do you have HPC / big NFS deployment users? | 17:35:22 |
