# Allow users of this group to interact with dhcpcd via the control socket. | |

# Inform the DHCP server of our hostname for DDNS. | |

# 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. | |
# Some non-RFC compliant DHCP servers do not reply with this set. | |
# In this case, comment out duid and enable clientid above. | |

# Persist interface configuration when dhcpcd exits. | |
persistent | |
# Rapid commit support. | |
# Safe to enable by default because it requires the equivalent option set | |
# on the server to actually work. | |
