 Arian | Just seems to need a rebase and a re-review | 15:49:10 |
| Arian | We did go into breaking changes freeze for 24.11 though. So idk if I can still merge it :/ | 15:49:31 |

| quyse | hi!
I'm using my custom NixOS AMI built with "${modulesPath}/../maintainers/scripts/ec2/amazon-image.nix" module. The EC2 serial console in the AWS web interface works (shows boot messages like it's a display), but "get system log" in the web interface, and the aws ec2 get-console-output command both always return empty output.
Is the system log thing even supposed to work? I am not very familiar with AWS, but I thought it works via the same mechanism as the EC2 serial console, and since the amazon-image.nix module enables serial console via kernel param (console=ttyS0), it should work too | 20:04:28 |

| Arian | This is expected for Nitro instances you need to call get-console-output with --latest | 20:13:04 |
| Arian | get-console-output without --latest is only available after instance termination | 20:13:28 |
| Arian | Or Connect -> EC2 Serial Console. Should work roo | 20:14:19 |
| Arian | * Or Connect -> EC2 Serial Console. Should work too | 20:14:26 |
| Arian | * get-console-output without --latest is only available after instance termination . Or around 15 minutes after the instance started | 20:14:45 |

get-console-output without --latest is only available after instance termination . Or around 15 minutes after the instance started oh, thank you very much! indeed it returns the output after termination. I wonder why the web interface doesn't warn about it | 20:17:25 |
| Arian | But the --latest flag should work too | 20:18:18 |
| quyse | In reply to @arianvp:matrix.org
But the --latest flag should work too yes, just tried it, it works! not immediately after instance launch, but quite quickly | 20:20:56 |
| quyse | interesting, after termination the output is again empty, with --latest or without | 20:27:40 |
| quyse | ok, a few more munutes after the termination get-console-output starts returning the full output again. I guess it's just a bit of weirdness on AWS side | 20:32:47 |

 tuxiqae | Arian: Thanks for the help the other day
I was able to write the following thanks to your help!

| 22:56:29 |
| tuxiqae | BTW, had to use 24.05 since AMI building in unstable seems to be broken due to hash mismatch in the getty package. Couldn't figure where the faulty hash is defined so I didn't fix it yet | 22:58:29 |

Smoke test
waiting for instance to be healthy.
hmmm
| 04:26:31 |
| Arian | Sometimes AWS just .... Doesn't work | 08:47:34 |
| Arian | I've had it before where instance just doesn't get into the healthy state and nothing was wrong | 08:47:53 |

 commiterate | Draft PR for amazon-ec2-net-utils: https://github.com/NixOS/nixpkgs/pull/355111
Someone will need to update the NixOS systemd libs to allow setting the [Install] options in the systemd unit config.
| 02:34:15 |
| colemickens | Oh no, sorry, it was just a joke about smoking. :( | 17:31:37 |
| colemickens | Though that does remind me, it maybe doesn't matter, but I am curious if you thought about using systemd-boot instead of grub on the EFI image.s | 17:32:19 |
| commiterate | I believe some instance types only support the legacy-bios boot mode which means we can't use systemd-boot for those. | 17:36:47 |
| Arian | It makes the build more complicated | 17:36:51 |
| Arian | And for x86 we don't have UEFI-only images. Just hybrid ones. And systemd-boot doesn't support that | 17:37:08 |
| Arian | Only grub | 17:37:10 |
| colemickens | I see, that probably explains the slightly odd (unaligned?) partition layout I was seeing in a booted instance with legacy bios partition. | 17:37:38 |
