 colemickens | weird. | 04:57:50 |
| colemickens | I'm trying to build diskoImagesScript on the aarch64 box for a hostPlatform.system = "aarch64-linux" machine and it's complaining that it wants an x86_64-linux builder for a qemu run-vm dep | 04:58:33 |
| colemickens | even weirder, it's a dep of an aarch64 output? | 05:00:54 |

| colemickens | error: a 'x86_64-linux' with features {} is required to build '/nix/store/wzab9w8ak2mafl1gxwi811lbc7pyjcgl-source.drv', but I am a 'aarch64-linux' with features {benchmark, big-parallel, gccarch-armv8-a, kvm, nixos-test}
| 05:01:13 |
| colemickens | odd, odd, odd. | 05:01:17 |
| colemickens | "aarch64-unknown-linux-gnu" looks like cross-comp but idk why | 05:02:10 |
| colemickens | I'm looking at how imageBuilderPkgs is defaulted/used and how host/buildPlatform are set for the system that includes this module and it seems like everything should be fine | 05:07:38 |
| colemickens | the next step would be vmTools, but also :/ I'm starting to doubt ? | 05:07:59 |
| colemickens | maybe this is vmTools use of buildPackages, and maybe I can just set customQemu and get around it | 05:14:34 |
| colemickens | well no that doesn't make sense, build and host is aarch64-linux. what the heck then. | 05:14:52 |
| colemickens | matthewcroughan: https://github.com/NixOS/nixpkgs/pull/325619 doesn't this kinda not work since ${qemu} is still used for making the empty disk image, etc? | 05:40:54 |
| colemickens | I'm so confused. If I build qemu_kvm or buildPackages.qemu_kvm it works, but if I build diskoImageScript it acts like it's crosscompiling from x86_64-linux. I've checked nixpkgs host/buildPlatform. :/ | 05:43:10 |
| colemickens | xargs cp :/ | 06:25:21 |
| colemickens | runs out of mem | 06:25:25 |

| colemickens | minus a couple small things, disko was great. got a gpt rk3588 uboot+roofs emmc image image, all automated with disko. | 07:47:18 |
| colemickens | truly much more pleasant that sdImage | 07:47:39 |
 matthewcroughan | In reply to @colemickens:matrix.org
xargs cp :/ OMG you found the reason for the out of mem? | 11:36:09 |
| matthewcroughan | Can we fix it | 11:36:11 |
| matthewcroughan | lassulus: | 11:36:26 |

| matthewcroughan | xargs cp is running out of mem apparently according to cole | 11:36:56 |
 lassulus | hm? I thought the xargs cp was used instead of the nix copy since it uses less memory? | 11:37:01 |
| matthewcroughan | * xargs cp is running out of mem apparently in disko according to cole | 11:37:01 |
| matthewcroughan | maybe both do and we still haven't found the reason, but it's interesting that cole identified it almost immediately | 11:37:25 |
| lassulus | yeah copying derivations is usually the step where we do OOM | 11:38:51 |
|  @shinri:zince.net left the room. | 12:37:47 |
| colemickens | no no | 14:57:14 |
| colemickens | so the issue is that there's a module option for memSize, that is ignored in the impure/script route. | 14:57:29 |
