>Description:

Installed net/isc-dhcp3-server from the port with the default options DHCP_PARANOIA and DHCP_JAIL. When the server is started for the first time, with the dhcp_chuser option selected in the config, the pid dir /var/run/dhcpd is created, but the pidfile is not written to it, even though the server is running.  chown-ing the pid dir to dhcpd:wheel allows the pid file to be written.

Sample output:


root at erwin:/root# ps ax | grep dhcp
57509  ??  Ss     0:00.00 /usr/local/sbin/dhcpd -cf /usr/local/etc/dhcpd.conf -lf /var/db/dhcpd/dhcpd.leases -pf /var/run/dhcpd/dhcpd.pid
