AVC for powertop
by William
Hi,
Running powertop as a confined staff_t/sysadm_t user on F20, I see the
following denial in permissive mode:
time->Tue May 13 14:34:12 2014

This works in unconfined_t obviously. What do you advise is the best way
forwards? To allow the read from staff_t/sysadm_t to cpu_device_t, or to
make a minimal policy around powertop (similar in the past to the iotop
policy you helped me create).
Sincerely,

iotop policy
by William
Hi Miroslav,
Did the iotop policy that you helped me with many months ago ever get
merged to selinux-targeted?

Where's findcon/indexcoin/replcon, setfilecon?
by dE
Hi,
These commands appear to be missing in fedora.
Package search (repoquery -q -f) didn't result in anything.
