The /etc/ub-dhcp/ub-dhclient.d directory allows other packages and system
administrators to create application-specific option handlers for ub-dhclient.
When ub-dhclient is run, any option listed in the dhcp-options(5) man page can
be requested. ub-dhclient-script does not handle every option available
because doing so would make the script unmaintainable as the components
using those options might change over time. The knowledge of how to handle
those options should be under the responsibility of the package maintainer
for that component (e.g., NTP options belong in a handler in the ntp
package).
To make maintenance easier, application specific DHCP options can be handled
by creating a bash script with two functions and placing it in /etc/ub-dhcp/
ub-dhclient.d
The script must follow a specific form:
(1) The script must be named NAME.sh. NAME can be anything, but it makes
sense to name it for the service it handles. e.g., ntp.sh
(2) The script must provide a NAME_config() function to read the options and
do whatever it takes to put those options in place.
(3) The script must provide a NAME_restore() function to restore original
configuration state when ub-dhclient stops.
(4) The script must be 'chmod +x' or ub-dhclient-script will ignore it.
The scripts execute in the same environment as ub-dhclient-script. That means
all of the functions and variables available to it are available to your
NAME.sh script. Things of note:
${SAVEDIR} is where original configuration files are saved. Save your
original configuration files here before you take the DHCP provided
values and generate new files.
Variables set in /etc/sysconfig/network, /etc/sysconfig/networking/network,
and /etc/sysconfig/network-scripts/ifcfg-$interface are available to
you.
See the scripts in /etc/ub-dhcp/ub-dhclient.d for examples.
NOTE: Do not use functions defined in /usr/sbin/ub-dhclient-script. Consider
ub-dhclient-script a black box. This script may change over time, so the
ub-dhclient.d scripts should not be using functions defined in it.

%description
The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on UDP/IP networks whereby a DHCP server dynamically assigns an IP address and other network configuration parameters to each device on a network so they can communicate with other IP networks.
%package devel
Summary: Development headers and libraries for interfacing to the DHCP server
Requires: %{name} = %{epoch}:%{version}-%{release}
%description devel
Header files for using the ISC DHCP libraries. The
libub-dhcpctl and libub-omapi static libraries are also included in this package.

# WARNING: This file is NOT used anymore.
# If you are here to restrict what interfaces should dhcpd listen on,
# be aware that dhcpd listens *only* on interfaces for which it finds subnet
# declaration in dhcpd.conf. It means that explicitly enumerating interfaces
# also on command line should not be required in most cases.
# If you still insist on adding some command line options,
# copy dhcpd.service from /lib/systemd/system to /etc/systemd/system and modify
# it there.
