| smoser | each time you do a request to the metadata service it ends up in lots of messages on the bus to get the information. at points you could almost DOS a openstack installation by just hitting the metadata server. | 13:42 |

| smoser | that is a very typical discussion on the topic. | 13:45 |
| smoser | i'd like to highlight this comment: | 13:45 |
| smoser | In these test runs, how long did it take cirros to boot? Lets say it took 2 minutes. That means you booted virtual hardware (bios, kernel,disk, ....) in 2 minutes, but a HTTP couldn't be satisfied in 10 seconds? | 13:45 |
| mock | Question: I am adding the package_update: true to my cloud-config userdata. My package manager is yum. Will this be the equivalent of a yum update or yum update --security? And if not the second, is there a cloud-init way to do the security only update or do I just need to runcmd the command. | 15:45 |
| mock | ? | 15:45 |
| Odd_Bloke | mock: I don't believe it will be the second, and I don't believe that there is a cloud-init way to express a security-only update. | 16:17 |
| Odd_Bloke | In the apt world, or Ubuntu at least, security updates aren't special at the package manager level; if you only want security updates, then you change the package sources to only include security repos and then `apt update; apt upgrade` as normal.) | 16:19 |
| Odd_Bloke | So I think this is a case where the "lowest common denominator" package management module can't express such a requirement (though I haven't given it too much thought and would happily be contradicted). | 16:20 |
| mock | Ok, thanks | 16:27 |
| mock | I will use the runcmd avenue | 16:28 |
