Description of problem:
SELinux is preventing /usr/lib/polkit-1/polkitd from 'read' accesses on the directory machine.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that polkitd should be allowed read access on the machine 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 polkitd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
