Cannot mask roonbridge service

Troubleshooting

I am having trouble masking the roonbridge service. Other services mask just fine. Is there a workaround?

Thanks for this report. Indeed there is an issue with masking custom services.

Systemd and Debian packages place their service unit files into /lib/systemd/system. When masking, a symlink to /dev/null (empty) will be created within /etc/systemd/system. Files there with the same name are handled as overwrites to the files in /lib/systemd/system, thus the service is empty then/nothing loaded.

The problem now is, that /etc/systemd/system is as well the desired location for customized or new service files, not created by systemd or APT packages. roonbridge.service is created by dietpi-software besides some other or our offered software services, especially where no APT packages are available. Thus all of them cannot be masked. The symlink location is already blocked by the manual service files.

Since DietPi handles it’s services by itself, thus disable it for systemd, there is currently no intended way to disable/mask them completely.

The best current way for you is to simply remove /etc/systemd/system/roonbridge.service.
You can recover it at any time from /DietPi/dietpi/conf/roonbridge.service.

I will implement a possibility to mask custom services for next DietPi version by renaming the service file back and forth.

I btw removed this feature from planned implementations. It makes things much too complicated. If one does not want DietPi to start/stop a service on boot and maintenance tasks, it can be excluded easily now via new dietpi-services 2.0 UI.
We might move DietPi services (and custom software services) to /usr/local/lib/systemd/system by times. Needs testing if this location is scanned. At least /usr/lib/systemd/system is, even that it is not documented anywhere.
/etc/systemd/system would then be used for masks only and drop-in .service.d/*.conf configs.
