SELinux has one Boolean for dhcpd:
dhcpd_disable_trans. This is the
standard Boolean for all targeted daemons, allowing you to disable the
transition from unconfined_t to
dhcpd_t. The value of this Boolean is
set to false by default.
This Boolean can be changed via the
system-config-securitylevel application or the
/usr/sbin/setsebool -P dhcpd_disable_trans 1 command.
Booleans are explained in Section 3.2 Files and Directories of the Targeted Policy.
