| chillysurfer | good day, all! i'm curious under what circumstance a network interface would be renamed to `cirename0`? briefly looking through the code isn't extremely obvious what the condition would be | 17:37 |

| powersj | chillysurfer, rharper's previous comment in https://bugs.launchpad.net/cloud-init/+bug/1852162 might be helpful | 17:41 |

| chillysurfer | powersj: so basically cloud-init uses cirename0 so that after a different interface setting (i.e. changed entwork adapters) it'll still retain the original and configured adapter names? | 17:57 |
| powersj | chillysurfer, I think that is how I read ryan's comment as well | 17:58 |
| chillysurfer | powersj: perfect thanks! | 17:58 |

| powersj | Krikke, the command you were looking for earlier is cloud-localds: https://cloudinit.readthedocs.io/en/latest/topics/faq.html#cloud-localds | 18:54 |
| powersj | handy way to produce an ISO with user data or metadata to then pass the disk to an instance | 18:54 |
| powersj | the doc above has some examples using qemu | 18:55 |
| rharper | chillysurfer: the 'cirename' prefix is used as a swap value; if we need to rename an interface (set-name in config); if we need to swap names (eth0 and eth1 names are reversed from a previous boot), then we cannot just rename eth0 to eth1; in those cases we use a cirenameX as placeholder; see cloudinit/net/__init__.py:_rename_interfaces(); | 19:05 |
| chillysurfer | rharper: thanks!! that makes total sense | 19:28 |
| rharper | chillysurfer: sure; in some failure paths, you'll see cirenameX still around; are you seeing that ? | 19:28 |
| chillysurfer | rharper: i don't think so but i'll validate that as well | 19:38 |
| Krikke | powersj: ah ok, the terraform scripts do it for me :) | 20:13 |
| giesen | Arghh lost hours because the documentation for static routes is partially incorrect with regards to Network Configuration v2. Submitted a pull request to fix it :)) | 23:26 |
