We are having an issue where we use a config folder to store secrets which is a read-only folder. The problem is that apparently there is some test step that runs when you upgrade the umbraco version, which prevents us from upgrading 12 to 13 atm. It checks using a hardcoded system-directories path "Constants-SystemDirectories" and there is even a TO-DO stating that it should probably be in the Umbraco folder. Is there some workaround we can do here? We are running a kubernetes setup and the folder is mounted making it readonly, and would like to not change that.
