| Odd_Bloke | smoser: I'm looking at fixing https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/1411582 in cloud-init. | 15:39 |
| Odd_Bloke | smoser: My suggested fix is to shift the udev rule that creates /dev/disk/azure/... in to cloud-init, and then teach cloud-init to dereference /dev/disk/... symlinks. | 15:40 |
| Odd_Bloke | smoser: We could also look at making the directory created more generic (e.g. /dev/disk/cloud-init/...), so that we have a single place to look for stuff on different clouds. | 15:41 |
| Odd_Bloke | (This would, for example, allow us to answer 'do I have an ephemeral disk?' by just looking at /dev/disk/cloud-init/ephemeral or whatever) | 15:42 |
| Odd_Bloke | smoser: Thoughts? | 15:42 |
| smoser | Odd_Bloke, well, looking forward, there is a plan for a block device usage languange. that explicitly declares how disks should be used. this will support raid, lvm, bcache ... | 17:02 |
| smoser | that is happening for curtin usage. | 17:02 |
| smoser | i'd like for cloud-init to be able to take that language and render it into being also. | 17:02 |
| smoser | the added piece that cloud-init needs is kind of what you were mentioning. curtin will be fed disk config like http://paste.ubuntu.com/10939715/ . | 17:07 |
| smoser | but ideally cloud-init can then allow substitution of things like 'ephemeral0' where it finds out what that is. | 17:08 |
| harlowja | larsks awesome | 17:23 |
| Odd_Bloke | smoser: Right, is that something that can happen now? We've got pressure from Azure to get this fixed. | 17:23 |
| Odd_Bloke | smoser: (Also, will we realistically ever take the curtin language in to 0.7.x?) | 17:24 |
| smoser | Odd_Bloke, probably not | 17:26 |
| smoser | Odd_Bloke, so i think i'm ok with the overall idea. | 18:00 |
| smoser | then cloud-init would allow users to specify 'ephemeral0' as they can elsewhere. | 18:00 |
| smoser | and on azure that would map to /dev/cloud-init/ephemeral0 | 18:00 |
| smoser | i think thats what you're saying | 18:00 |
| Odd_Bloke | smoser: Yeah, it would be /dev/disk/cloud-init/ci-ephemeral or somesuch. | 18:16 |
| Odd_Bloke | smoser: Ben proposed this udev config: http://paste.ubuntu.com/11566987/ | 18:16 |
| smoser | it doesnt seem unreasonble. | 18:17 |
| smoser | but i dont know how this determines between "running on azure" and "running on hyper-v" | 18:18 |
| alexpilotti | smoser: this is for cirros? | 18:19 |
| smoser | alexpilotti, that above was azure ubuntu | 18:19 |
| alexpilotti | oh, k tx | 18:20 |
| Odd_Bloke | smoser: I'm not sure either; udev is not my strong suit. Let me check with Ben. | 18:20 |
| Odd_Bloke | smoser: Ben confirmed with Microsoft that that would only match in Azure environments. | 18:23 |
| smoser | why would they only match in azure | 18:27 |
| smoser | that is odd | 18:27 |
| smoser | dont you think ? | 18:27 |
| smoser | ID_VENDOR of Msft | 18:27 |
| smoser | odd | 18:27 |
| Odd_Bloke | smoser: I _think_ it's the UUIDs that are Azure-specific. | 18:35 |
| smoser | ah. that does seem more reaosnable. | 18:36 |
| alexpilotti | smoser: I’m hearing about ext4 for config drives | 21:16 |
| smoser | alexpilotti, that is odd / roughly stupid | 21:48 |
| smoser | not really here. but a link to info woudl be good. but really cloud-init doesnt care. | 21:49 |
| harlowja | windows dll fun scares me lol | 23:35 |
