 matthewcroughan | Something that should never change is the ${device}-part1 ${device-part2}, so maybe I can just use that, since the kernel is responsible for keeping that stable | 16:10:44 |

 lassulus | No example ready now. But just run env in a hook to see what's available | 16:28:18 |

| 17:36:50 |
| matthewcroughan | it starts at 2048 | 17:37:00 |
| matthewcroughan | fdisk -x says First usable LBA: 34 | 17:37:18 |
| matthewcroughan | So:
content = {
type = "gpt";
partitions = {
bl2 = {
start = "34";
end = "8191";
Didn't quite do what I was looking for
| 17:37:37 |
| matthewcroughan | Is that supposed to have worked, or am I misunderstanding something? | 17:37:46 |
| lassulus | Not sure what sgdisk is doing there | 17:38:38 |

| matthewcroughan | here's the diskoScript | 17:39:08 |
| matthewcroughan | Maybe it is the --align-end flag? | 17:40:35 |
| matthewcroughan | Yeah I set alignment = 1 and it's good now lassulus | 17:45:14 |

IO error: Operation not permitted
| 17:54:16 |
| matthewcroughan | Although mkfs.bcachefs crashes the diskoScript and prevents the postCreateHook from executing | 17:54:32 |
| matthewcroughan | With IO error: Operation not permitted | 17:54:38 |
| matthewcroughan | running the mkfs.bcachefs command directly doesn't exhibit the permission error | 17:59:40 |
| matthewcroughan | maybe something isn't settling? | 18:00:34 |
| matthewcroughan | changing the FS to ext4 makes it work correctly, this is odd stuff | 18:02:05 |
| lassulus | Maybe it has to do with the alignment changes you did? | 18:04:58 |
| matthewcroughan | But if I run the mkfs.bcachefs cmd from the set -x debug manually by hand after it exists, I don't get the "Operation not permitted" error | 18:06:04 |

| matthewcroughan | And if I use ext4, everything is fine too. | 18:06:33 |
| matthewcroughan | Yeah, something about the assumptions of the diskoScript don't work on real hardware like this SD card | 18:21:12 |
| matthewcroughan | I've tried two SD cards in two interfaces by now | 18:21:27 |
| matthewcroughan | trying another medium | 18:22:46 |
| matthewcroughan | figured it out | 18:23:25 |

| 18:23:27 |
| matthewcroughan | it's the touch /mnt/disko-first-boot | 18:23:34 |
| matthewcroughan | works with ext4, doesn't work with bcachefs | 18:23:47 |
