Dear fellow selinux experts,
I am trying to make one of my machines a dhcp server to connect other
machines to the internet, see thread in Fedora list if applicable, I
have achieved a breakthrough, but selinux denies it :(

20:03:40 localhost dhcpd: Can't create PID file /var/run/dhcpd.pid:
Permission denied.
How can I allow it to work?
Setroubleshoot has not kicked in to warn me so I do not know a fix as
of this moment :(
/var/run/dhcpd.pid should be dhcpd_var_run_t, not var_run_t.
Try:
# restorecon -v /var/run /var/run/dhcpd.pid
