 Crony Akatsuki (balkan/slav) | np, tho that will prob be tomorrow for me (it's 7pm here, gonna go to sleep soon) | 18:04:34 |
 magic_rb | 7pm here too :P | 18:04:48 |
| magic_rb | My sleep schedule is just fucked up | 18:04:54 |
| Crony Akatsuki (balkan/slav) | my sleep schedule moves according to my work, sometimes I wake up at 3am sometimes at 8am | 18:05:22 |

| matthewcroughan | How does the CI not catch this? | 16:35:10 |
 Mic92 | Maybe it's not reproducing in other machines that are not yours. | 16:35:59 |
| matthewcroughan | the fact that the disko image builder, inherits the kernel of the caller, is an architectural mistake, don't you think? | 16:36:23 |
| matthewcroughan | this means CI can't really tell you anything | 16:36:38 |
| matthewcroughan | and in the case of building images for a raspberry pi, that will never work | 16:37:17 |
| matthewcroughan | because this kernel is specific to the Pi, and won't boot under qemu | 16:37:26 |
| Mic92 | not sure we test on aarch64 at the moment | 16:37:41 |
| matthewcroughan | ah that too | 16:37:45 |
| matthewcroughan | but this is x86 in my case anyway | 16:37:55 |

| matthewcroughan | That's my disko config | 16:38:28 |
| matthewcroughan | I was thinking btw, disko could auto generate the networking.hostId based on a hash of the device | 16:38:52 |
| matthewcroughan | * I was thinking btw, disko could auto generate the networking.hostId based on a hash of the device in pure nix | 16:38:55 |
| matthewcroughan | one less thing to worry about | 16:39:01 |
| Mic92 | in srvos we set a fixed hostid | 16:39:43 |
| Mic92 | But it feels a bit overarching for disko to set this. It's a disk partitioning framework | 16:40:19 |
| Mic92 | * in srvos we set a fixed hostid for all machines | 16:40:24 |
| Mic92 | * But it feels a bit overarching for disko to set this. It's a disk partitioning framework and this feels more like general NixOS configuration | 16:40:42 |
| matthewcroughan | Ah sure, I guess you could just do the hashing trick that I mentioned in your own config | 16:47:24 |
| Mic92 | honestly I don't think this even needs hashing | 16:48:39 |
| Mic92 | I have seen no usecase yet for a per machine hostid, except if you have zfs hosted on iscsi network block devices and want to prevent accidents. | 16:49:11 |
