Former:

# A sample configuration for dhcpcd.
# See dhcpcd.conf(5) for details.

# Inform the DHCPv4 server of our hostname for DDNS.
# This has been superceded by the FQDN option below, but is included
# by default for servers which do not understand it.
hostname

# Inform the DHCP server of our hostname for DDNS
# and/or query for what it should be.
fqdn

# Use the hardware address of the interface for the Client ID.
#clientid
# or
# Use the same DUID + IAID as set in DHCPv6 for DHCPv4 ClientID as per RFC4361.
duid

# Rapid commit support.
# Safe to enable by default because it requires the equivalent option set
# on the server to actually work.
option rapid_commit

# A list of options to request from the DHCP server.
option domain_name_servers, domain_name, domain_search, host_name
option classless_static_routes
# Most distributions have NTP support.
# option ntp_servers
# Respect the network MTU.
# Some interface drivers reset when changing the MTU so disabled by default.
#option interface_mtu

# A ServerID is required by RFC2131.
require dhcp_server_identifier

# A hook script is provided to lookup the hostname if not set by the DHCP
# server, but it should not be run by default.
nohook lookup-hostname

# Use this to define the lease time (in seconds).
#leasetime 60

# Use a 90 second timeout after which we abort the DHCP negotiation
timeout 30
reboot 30
# Use an infinite timeout so we never fallback to a static IP.
#timeout 0

# Don't attempt to obtain an IPv4LL address if we failed to get one via DHCP.
noipv4ll

# Only configure IPv4.
#ipv4only

# Be sure to handshake our vendor code (for interoperability with NNIT).
vendor 01,"0"

# Do not want stateless autoconf if dhcp is used
ipv6ra_noautoconf

# Use the last lease if there is one when no DHCP server is available (and
# until the lease actually expires)
lastlease

#debug

...and:

[NetAcq99793214:~]# ps -ef |grep dhcpcd
