Yes, I realize the idea is quite cursed. The main idea is to minimize stress on the control node, so a centralized cache or pxe server for the full filesystem is a no-no. All filesystems have to be reformatted on reboot, including /nix/store. We already have a setup like this working with Debian, but it's hacked together using shell-scripts, python, and preseed files. Hence I am investigating alternatives. :) I do not have the overview over your setup/requirements, but i use this PXE setup as an installer. There are many options, such as overlayfs, that you use here to customize it. | 13:40:15 |
 lillecarl | @kacper.uminski:matrix.org: Boot off iPXE, dd the image to disk, kexec, rebuild. You can have multiple cache servers and will easily be able to saturate your links with NGINX from *a few* cache servers. You can share the same signing key across them and use RR DNS for loadbalancing.
The torrent thing sounds like a solution to "immutable Debian" rather than content delivery | 13:46:19 |
| lillecarl | It'll be faster, no torrent startup time, only fetch what your node needs etc... :) | 13:50:16 |
 Kacper Uminski | Hmm, I will try this. Thank you! | 13:53:24 |
| Kacper Uminski | Just by the way, I am quite new to netbooting as a whole, so I do ask for leniency anytime I utter something unspeakably stupid. :) | 13:58:58 |
| markuskowa | Kacper Uminski: I run a small hpc cluster (20 nodes) at Fysikum, SU fully on NixOS. If you're interested i can show, how it is setup. | 15:42:05 |
| Kacper Uminski | That would be very cool! Do you have a git repo for it or something? | 15:47:29 |
| markuskowa | No, I did not publish the configuration for security reasons. | 15:49:23 |
| Kacper Uminski | Ah, yeah, that's reasonable. | 15:49:51 |
| lillecarl | https://github.com/aristanetworks/nix-serve-ng Arista Networks reimplementation of nix-serve in Haskell that's supposed to be superduperfast. Kacper Uminski 😄 | 21:37:35 |
| lillecarl | Can LIU subsidize you coming up to Stockholm to drink beer with us on the 30th? | 21:38:08 |

Can LIU subsidize you coming up to Stockholm to drink beer with us on the 30th? No, sadly. I'm just a student, not an employee, and LiU is not very spend-happy right now. The only reason Lysator got to keep its server room was because we rode the AI bubble and promised to build an AI cluster. :( | 21:42:23 |

 adisbladis | That's the kind of thing I'm trying to accomplish with https://github.com/adisbladis/adios/ | 05:25:48 |
| lillecarl | Beware that COVID is running rampant right now in Stockholm guys! | 17:29:42 |

 talyz | Meetup today or no? | 08:18:46 |
| markuskowa | Yes, absolutely! | 08:19:13 |
| markuskowa | 1800 today at the Nordic Light hotel. I'm probably half an hour late. | 14:58:59 |
 Claes | Very much more people here than usually | 16:01:49 |
| Claes | Other people :-) | 16:02:01 |
| talyz | On my way now | 16:04:36 |
| Claes | I am sitting more on the side due to the crowd | 16:07:28 |
| Claes | next to the street | 16:07:40 |
| lillecarl | Damn I forgot it's today 🤣 | 20:44:02 |
| lillecarl | The positive thing is someone else got the opportunity to talk then, heh | 20:44:39 |

The positive thing is someone else got the opportunity to talk then, heh we thought it was Covid! | 19:45:09 |
| lillecarl | Haha I was early on this "covid season" so it's already passed | 23:14:00 |
| lillecarl | I've got updates: dinix is finished (generate dinit configs with NixOS module system). nix-csi is alpha-quality (still need to clean up the deployment so it's usable for others). I've managed to run NixOS with it as a privileged container, nixNG as unprivileged. It's managing gcroots and hardlink directories properly etc.
Upcoming projects:
- finish nix-touch/nix-timegc (update packages regtime and use regtime in GC) (I wanna use it for nix-csi to keep build tools around without installing gcroots for them)
- build a terranix clone for terragrunt
- build a stateful kubectl apply tool (Maybe just terraform)
And I've got a gig at an old employer as a consultant, gonna build a small-scale but fully featured Kubernetes thingy

AAAND: ChromeOS is removing the dumb unprivileged LXC layer from their Linux VM thingy so "soon" we'll be able to run NixOS proper on Chromebooks (The new Lenovo CB 14 is sicccc)
