If I manually run "/usr/lib/rtkit/rtkit-daemon" it works just fine...
The only problem is when I start it with "systemctl start rtkit-
daemon.service".
I strace it and from the log it seems it succeeds to open dbus socket:
[...]
connect(3, {sa_family=AF_UNIX, sun_path="/var/run/dbus/system_bus_socket"}, 
33) = 0
getsockopt(3, SOL_SOCKET, SO_PEERCRED, {pid=1, uid=0, gid=0}, [12]) = 0
fstat(3, {st_mode=S_IFSOCK|0777, st_size=0, ...}) = 0
getsockopt(3, SOL_SOCKET, SO_ACCEPTCONN, [0], [4]) = 0
getsockname(3, {sa_family=AF_UNIX}, [128->2]) = 0
geteuid()                               = 1000
sendmsg(3, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\0AUTH EXTERNAL 
", iov_len=15}, {iov_base="31303030", iov_len=8}, {iov_base="\r
\nNEGOTIATE_UNIX_FD\r\nBEGIN\r\n", iov_len=28}], msg_iovlen=3, 
msg_controllen=0, msg_flags=0}, MSG_DONTWAIT|MSG_NOSIGNAL) = 51
[...]
