OEM configuration

The coreos.oem.* parameters follow the os-release spec, but have been repurposed as a way for coreos-cloudinit to know about the OEM partition on this machine. Customizing this section is only needed when generating a new OEM of CoreOS from the SDK. The fields include:

• id: Lowercase string identifying the OEM
• name: Human-friendly string representing the OEM
• version-id: Lowercase string identifying the version of the OEM
• home-url: Link to the homepage of the provider or OEM
• bug-report-url: Link to a place to file bug reports about this OEM

coreos-cloudinit renders these fields to /etc/oem-release. If no id field is provided, coreos-cloudinit will ignore this section.

For example, the following cloud-config document...

#cloud-config
coreos:
  oem:
    id: "rackspace"
    name: "Rackspace Cloud Servers"
    version-id: "168.0.0"
    home-url: "https://www.rackspace.com/cloud/servers/"
    bug-report-url: "https://github.com/coreos/coreos-overlay"

...would be rendered to the following /etc/oem-release:

ID=rackspace
NAME="Rackspace Cloud Servers"
VERSION_ID=168.0.0
HOME_URL="https://www.rackspace.com/cloud/servers/"
BUG_REPORT_URL="https://github.com/coreos/coreos-overlay"
