> When application is installed, a container will be launched with **root** privileges.
> This is required in order to apply the correct permissions to the `mariadb` directories.
> Afterwards `mariadb` will start as a **non**-root user (`999`).>
> On each upgrade, a container will be launched with **root** privileges in order to
> apply the correct permissions to the `mariadb` **backups** directory.
> Container that performs the backup will run as a **non**-root user (`999`) afterwards.
> Keep in mind the permissions on the backup directory will be changed to `999:999` on **every** update.
> But will only be changed once for the `mariadb` data directories.
