Qubes OS version:

R4.0

Description

Right now there is no mechanism for register supported services. One can enable/disable service with qvm-service (or GUI VM settings) with arbitrary name. If that name is recognized by the VM's scripts, it will act upon it. If not - it will be silently ignored. This means for example typos are impossible to detect at service setting stage.

It would be useful to have some mechanism VM could use to advertise support for a service. This would help UI to detect common mistakes, but also to present appropriate settings (for example disable settings not supported in given VM). We have qubes-firewall feature to advertise qubes-firewall service support, but more generic mechanism is needed.

Proposed solution: introduce supported-service.* features and allow VMs to request enabling/disabling them.

It should still be possible to set arbitrary service, but tools could warn if such service is not advertised as supported.

ext/services: mechanism for advertising supported services
6639401 
Support 'supported-service.*' features requests coming from VMs. Set
such features directly (allow only value '1') and remove any not
reported in given call. This way uninstalling package providing given
service will automatically remove related 'supported-service...'
feature.
