ReadOnlyDirectories=... for whitelisting files for a service.
* libsystemd-bus:
- - default policy (allow uid == 0 and our own uid)
- - access policy as vtable flag
- when kdbus doesn't take our message without memfds, try again with memfds
- implement translator service
- implement monitor logic
* priority queues
* priority inheritance
- sort out error codes for sd_bus_release_name(), distuingish: successful removal from foreign name, from non-existing name
+ - bug in kdbus: nameownerchange is not generated for names, only ids.
+ - kdbus: matches against source or destination pids for an "strace -p"-like feel. Problem: The PID info needs to be available in userspace too...
+ - kdbus: we need a way to distuingish messages we got due to monitoring from normal messages, since we want to bind methods only to the latter
+ - figure out what to do when fields in the kdbus header and in the payload header do not match
* sd-event
- allow multiple signal handlers per signal
