Just a note regarding template updates.
Since Unraid 6.2, the OS has automatically updated templates to always reflect the currently available version. (IE: It will add in any missing path, port, variables that the user's template does not have).
This was done on the theory that a new update to the container may also require any missing new entries. This behaviour has been troublesome for certain templates and how some users configure their systems. A flag to indicate to the OS to not update the templates has been in place to avoid this:
<TemplateURL>false</TemplateURL>
Starting however with the release of Unraid 6.10-rc3+ the system will no longer automatically update user's templates. Effectively this means that should you issue an update to the container which requires an update to the template you will need communicate this to the users via your support venues.
Currently, CA (and FCP) will still ensure that the templates are still being updated on versions of the OS < 6.10. If this change in the OS proves to lessen support requests to the maintainers, then CA and FCP will be modified to prevent those legacy versions of the OS from also updating the templates.
IE: If you were using the above flag to signal to the system to not update the templates, you should continue to do so.
