Steps

If this service has native support for Link or Symlink:

• Start a RFC to describe the way to implement the virtual_link feature (take this issue as the tracking issue)
• Implement the RFC
• Setup linker tests

Services

If the service does not support CreateLink, please mark it as done and leave a comment.
