 matthewcroughan | something wants to get out and log, but not sure what | 18:56:09 |

| matthewcroughan | The issue goes away with increased memSize | 18:57:39 |
| matthewcroughan | I guess this is another bug, but somehow logging doesn't catch it | 18:57:50 |
| matthewcroughan | * I guess this is another bug, but somehow logging doesn't work this time around | 18:58:00 |
| matthewcroughan | Is there any opposition for a general purpose compression command lassulus ? | 19:04:47 |
| matthewcroughan | I already tried this once and you said no, that others should configure it themselves | 19:04:57 |
| matthewcroughan | But IMO it should not be, it should be an option like it is in repart | 19:05:08 |
| matthewcroughan | https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/image/repart.nix#L152-L171 | 19:05:26 |
| matthewcroughan | * I already tried this once and you said no, that others should configure it themselves in extraPostVM | 19:05:49 |
| matthewcroughan | Like right now I'm writing a wrapper that lets somebody do it | 19:10:12 |
| matthewcroughan | disko.imageBuilder.extraPostVM = lib.optionalString cfg.image.embedUboot ''
${lib.getExe' pkgs.coreutils "dd"} conv=notrunc,fsync if=${cfg.platformFirmware}/u-boot-rockchip.bin of=$out/${config.disko.devices.disk.disk1.imageName} bs=512 seek=64
'' + lib.optionalString cfg.image.disko.compress ''
${pkgs.zstd}/bin/zstd --compress $out/*raw
rm $out/*raw
'';

| matthewcroughan | It ends up looking like this | 19:10:23 |
| matthewcroughan | but I don't like that | 19:10:30 |
| matthewcroughan | instead it'd be nice if I could just set disko.imageBuilder.compression.enable = true | 19:11:03 |

error: Unsupported OVMF projectDscPath on armv6l
| 21:32:37 |
| matthewcroughan | disko's image builder doesn't support armv6 | 21:32:43 |
| matthewcroughan | might be my fault 🧠| 21:36:43 |
| matthewcroughan | https://github.com/nix-community/disko/pull/643/changes | 21:36:45 |
| matthewcroughan | Then after you fix that, you can't use disko anyway since disko needs qemu in order to build images | 22:02:28 |
| matthewcroughan | spandsp-aarch64-linux> checking for ld used by armv6l-unknown-linux-gnueabihf-gcc... armv6l-unknown-linux-gnueabihf-ld
error: Cannot build '/nix/store/qjr624zrczgfj4vy6bpxiygaaf15xq6v-qemu-armv6l-unknown-linux-gnueabihf-10.2.2.drv'.
| 22:02:30 |
| matthewcroughan | which doesn't work because spandsp doesn't build and work on armv6l | 22:02:39 |
| matthewcroughan | looks like disko is using a fuller qemu than it needs to ? | 22:11:28 |
| matthewcroughan | You can set disko.imageBuilder.qemu, but why does disko default to a qemu that has gtk and opengl support? | 22:11:48 |
| matthewcroughan | Looks like the lib/make-disk-image.nix hardcodes virtio_pci, which won't work on armv6 either | 22:15:02 |
