Where does qubesdb-write write?

Hi,

Where exactly does qubesdb-write write the data?

What RPC policy is necessary for qube A to be able to read/write /somepath of qube B? (but no other paths)

What can this be used for (safely)?

qubesdb itself is not persistent and not shared between different qubes in any way (there is no “permission” to do that, this feature simply doesn’t exist, by design). It’s only a mechanism for dom0 to provide some information to the qube and sometimes for the qube to provide some information to dom0. Most of those are documented at Qube configuration interface | Qubes OS
