I can't restart services as root on CentOS.
Unable to register authentication agent: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.PolicyKit1 was not provided by any .service files
The polkit service isn't starting at boot.
$> systemctl status polkit
● polkit.service - Authorization Manager
Loaded: loaded (/usr/lib/systemd/system/polkit.service; static; vendor preset: enabled)

If I try to start it manually:
$> systemctl status polkit
● polkit.service - Authorization Manager
Loaded: loaded (/usr/lib/systemd/system/polkit.service; static; vendor preset: enabled)
Active: active (running) since Wed 2016-12-07 11:15:26 GMT; 2s ago

That permission denied error is suspicious (nevertheless the service seems to be running).
$> ls -l /usr/share/ | grep polkit-1

I have moved /usr/share and a few other post-initial-installation files to a NFS share. Yet the above permissions seem to be correct and /usr/share/polkit-1 is a symlink to a directory on the local filesystem.
Now if do something like this:
$> service network restart
the virtual machine network icon flashes for a moment but then the whole machine locks up completely. systemctl restart network fails the same way.
My original theory was that dbus was failing because inotify is not supported on NFS.
$> systemctl status dbus -l
...
Cannot setup inotify for `/usr/share/dbus-1/...
I then moved /usr/share/dbus-1 back to the local filesystem (via soft link) and rebooted, systemctl status dbus -l seems to say everything's fine, up until I run service network restart at which point the whole machine locks up with a policykit error. I moved /usr/share/polkit-1 to the local filesystem and that brings us to here.
What's wrong with policykit? Or rather, why can't services start?
