 raitobezarius | that's just dd right? | 09:01:19 |
 K900 | I mean in a way that doesn't involve dd | 09:02:21 |
| raitobezarius | hmmm I don't think so | 09:02:30 |
| raitobezarius | you could | 09:02:33 |
| raitobezarius | cursedly | 09:02:35 |
| raitobezarius | create a new partition | 09:02:38 |
| raitobezarius | and make a multi disk bcachefs thingie? | 09:02:44 |
| raitobezarius | you're welcome | 09:03:00 |
| K900 | Uhh | 09:03:02 |
| K900 | dd time | 09:03:04 |
| K900 | OK dd time succeeded | 09:15:40 |
| K900 | (or rather, sfdisk time) | 09:15:50 |

 steveej | i'm working on a nixos config for a cloud-hypervisor based hosting platform. they load the kernel and initram directly without a bootloader. they hardcode calling /init. now i'm looking for a way to replace the /init. i've accepted the fact that i won't be able to do fallback for now. what is the right place in a config to execute this? i'm thinking of boot.loader.external.installHook but don't fully understand the context it runs in | 09:41:28 |

| K900 | What we've done in NixOS-WSL is use an activation script to inject a binary there | 09:43:43 |
| K900 | That looks something like this: https://github.com/nix-community/NixOS-WSL/blob/main/utils/src/shim.rs | 09:44:21 |
| K900 | You probably want to do something similar | 09:44:27 |
| K900 | (or even steal that one wholesale as I'm pretty sure it doesn't have any WSL specific hacks left) | 09:44:39 |
| steveej | i thought about an activation that too. does that work in the nixos-rebuild boot case? i thought it's only executed when the new system is booted, which in my case relies on /init pointing to the new system | 09:47:41 |
| K900 | It doesn't, no | 09:48:33 |
| K900 | The more correct way to do it would be through a bootloader script, yes | 09:48:43 |
| K900 | But the important thing here is that you can't just symlink NixOS init to the right place and expect it to work | 09:49:01 |
| K900 | Because normally activation happens before that | 09:49:06 |
