This is unixish way to access to system resources via filesystem.
At this time just wrapper over DBus which wraps requests to DBus behind filesystem based on FUSE.
To use RDFS you must configure PAM to create new namespace on session startup:
/etc/pam.d/system-auth:
... session required pam_namespace.so ...
/etc/security/namespace.conf:
/rdc /rdc-inst/ user
Then create directory /rdc with mode 0700.
Now every users will have directory /rdc in own namespace for each session.
When user runs rdfs /rdc some directories will appears in this directory:
[zert@zert]:~ $>> ls -1 /rdc/ dbus rd
Directory dbus contains DBus resources in file representation. Directory rd just reserved for further usage.
