Hello,
Since the release of fedora-18, there are some regressions related to tuned package. It is
regression compared to Beta. tuned service does not start because of various
reasons[1][2][3].
One option is to drop tuned usage, another is to push fedora into fixing these.
A fix for [3] is available, but has not been pushed yet.
Regards,
Alon
