DESCRIPTION
Manage an ISC DHCP server service in a chroot environment.
SUPPORTED PARAMETERS
config
The absolute path to the DHCP server configuration file.
(unique, required, string, no default)
chrooted
Configure the dhcpd service to run in a chrooted or non-chrooted mode.
(unique, optional, boolean, default true)
chrooted_path
The absolute path of the chrooted DHCP environment.
(unique, optional, string, default "/var/lib/dhcp")
binary

includes
This parameter provides a means to copy include files into the chrooted environment. If a dhcpd.conf file contains a line similar to

list.
(optional, string, no default)

(optional, string, default "/db/dhcpd.leases")
pid
