If problems still persist, please make note of it in this bug report. I just got this denial, but I have selinux-policy-3.9.16-15.fc15 installed already Please show us the actual avc ausearch -m avc -ts recent Also if you run the AVC though audit2allow, what does it say ausearch -m avc -ts recent | audit2allow it returns just <no match>
looking at man page, I've replaced 'recent' (10 minutes) with 'today'
# ausearch -m avc -ts today

looking at setroubleshoot report there is:
SELinux is preventing /bin/systemctl from search access on the directory 1.
***** Plugin catchall (100. confidence) suggests ***************************
If you believe that systemctl should be allowed search access on the 1 directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep telinit /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
