Well progress is better than yesterday, dhcpd fails but today I still
have internet.  Following are the amended dhcpd.conf and the avc denials
in case they give a clue to what's happening.

[root dell ~]# cat /etc/dhcpd.conf
#Sample /etc/dhcpd.conf
# (add your comments here)
ddns-update-style none;
default−lease−time 600;
max−lease−time 7200;
option subnet−mask 255.255.255.0;
option broadcast−address 192.168.1.255;
option routers 192.168.1.254;
#option domain−name−servers 192.168.1.1, 192.168.1.2;
#option domain−name "mydomain.org";
authoritative;
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.100 192.168.1.199;

}
[root dell ~]#

[root dell ~]# service dhcpd start
Starting dhcpd:                                            [FAILED]
[root dell ~]#

When running restorecon /etc/dhcpd.conf the avc message is:

SELinux is preventing restorecon (setfiles_t) "read write"
unconfined_t. 

When restarting the network there are 3 messages:

SELinux is preventing pppd (pppd_t) "read write" unconfined_t. 
SELinux is preventing arping (netutils_t) "read write" unconfined_t. 
SELinux is preventing ip (ifconfig_t) "read write" unconfined_t. 

When starting dhcpd :

SELinux is preventing dhcpd (dhcpd_t) "read write" unconfined_t. 

I hope this means something to someone.
