 Kacper Uminski | Thanks! I will investigate this, at least for the minimal bootup. :) | 13:36:27 |
 lillecarl | @kacper.uminski:matrix.org: do you work for a VPN company perhaps? 😄 | 13:37:46 |
| Kacper Uminski | No, I'm just a member of Lysator (lysator.liu.se), a computer association in Linköping, and we are currently building an HPC cluster. Just as a cool tidbit, Nationella Superdatorcentrum (NSC) does the torrent-boot thing. | 13:39:00 |

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 |
