# If remaining is true (default), udhcpd will store the time

# remaining for each lease in the udhcpd leases file. This is

# for embedded systems that cannot keep time between reboots.

# If you set remaining to no, the absolute time that the lease

# expires at will be stored in the dhcpd.leases file.

# The time period at which udhcpd will write out a dhcpd.leases

# file. If this is 0, udhcpd will never automatically write a

# lease file. (specified in seconds)

# DHCP decline message is received (seconds).

# as the dns option, they can be listed on the same line, or multiple

# lines. The only option with a default is 'lease'.
