Non-persistent OS customization spec for Linux does not copy extension data - customization fails #623

Closed davdmrgn closed 9 months ago

davdmrgn commented 9 months ago

Describe the bug

Deploying a VM where a static IP is required while using an OS customization specification requires a copy of an existing OS customization spec, typically non-persistent as it is only used to deploy that virtual machine.

When creating a new OS customization spec from an existing one, data stored for Linux servers (time zone, scripts, etc) are buried under extensiondata in a separate, non-writable object and is not copied to the new non-persistent OS customization spec.

Work-around

Create a persistent customization spec for your deployment, and manually delete it afterwards. Creating a new persistent customization spec from an existing one copies the extension data required for Linux customization.

Reproduction steps

  1. Create a persistent Linux OS customization specification, with data in the script field
  2. Copy that Linux OS customization specification to a non-persistent customization specification
  3. View the extension data of both
  4. The non-persistent OS customization spec does not have extension data for Linux, causing customization scripts to not run ...

Expected behavior

Creating a non-persistent OS customization spec should copy all data required for Linux.

Furthermore, there are fields available in the primary object - these data could be stored there to ensure they're copied, rather than having it buried in another object under extension data.
