<pre>Can't elevate process scheduling from normal to real time (fifo), neither as a
normal user or root. It's a fully updated archlinux system with the just
released systemd 218.
Steps to reproduce:
Look for this rtkit-daemon log output, when it starts:
rtkit-daemon[10832]: Successfully called chroot.
rtkit-daemon[10832]: Successfully dropped privileges.
rtkit-daemon[10832]: Successfully limited resources.
rtkit-daemon[10832]: Running.
rtkit-daemon[10832]: Canary thread running.
rtkit-daemon[10832]: Failed to make ourselves RT: Operation not permitted
rtkit-daemon[10832]: Watchdog thread running.
downgrade to systemd 217
notice that rtkit-daemon does not outputs "Failed to make ourselves RT:
Operation not permitted" anymore and any process that request real time
scheduling (like jack) will now work properly.</pre>
