There was a problem hiding this comment.
reusing err in here always feels fixy. Can we use the common if err := ... form?

this adds an additional check to the windows_svc_config startup routine to verify permissions for the configured root directory. I do not love the concept of adding an explicit denial instead of just removing the existing grant, but this has been the only way i've seen success so far, after trying several different ways to do this.
Once the changes run I am no longer able to create/write nested directories inside of the root directory without using an admin console. Subsequent runs see the entry exists and skip before making further changes.
Follow up PRs will attempt to set the proper directory permissions on package install
