 Arian | If any of the AWS folks I met at NixCon are in this room. WHY DIDN'T YOU TELL ME THIS WAS A THING YOU'RE WORKING ON THIS IS AMAZING | 14:18:12 |

 commiterate | now if only there was Cfn support for ImportSnapshot-based AMIs | 05:08:23 |
| Arian | they don't do importsnapshot here. they use EBS-Direct | 16:29:54 |
| commiterate | the main annoyance with using EBS direct (via coldsnap) is lifecycle management. You get that for free with Terraform/OpenTofu or Cfn, with Cfn having the extra benefit of auto-rollback and not needing to burn compute time when updating stacks. | 19:30:08 |
| commiterate | trying to escalate that feature request by pulling in the people who worked on the attestation examples. EC2 has provided a pretty concrete use case themselves | 19:59:16 |

| Arian | Have you looked at the repart appliance image tests? | 11:31:36 |
| Arian | What I'd do is make the AMI EBS Volume an EROFS volume. Then overlay mount the rootfs over it | 11:33:05 |
| Arian | and that can be on the instance store or whatever | 11:33:30 |
| Arian | or just... only mount /var to the instance store | 11:33:37 |
| Arian | Do you want to be able to have interactive nix usage afterwards? | 11:33:44 |
| 21 Aug 2025 |
| commiterate | These tests?

| commiterate | I considered overlayfs but it doesn't seem to cache reads from the lower filesystem (whatever's on the EBS volume) to the upper filesystem (whatever's on the instance store). | 02:45:40 |
| commiterate | I'm not too sure what counts as interactive Nix usage, but these will be CI/CD runners so users should be able to do a nixos-rebuild switch afterwards to modify the environment (e.g. set up Docker Engine). | 02:47:12 |
| commiterate | That makes mounting something at / attractive since users don't need to remember to write under a special directory to hit the instance store instead of the root EBS volume. | 02:58:36 |
| commiterate | * That makes mounting something transparent at / attractive since users don't need to remember to write under a special directory to hit the instance store instead of the root EBS volume. | 03:02:34 |
| Arian | Ah so you're worried that all the nix store paths in the lower store will have slow access? | 12:26:42 |
| commiterate | Yup. | 16:25:30 |
