 dhcpcd-9 requires this directory and contents to be writeable by the

-The Makefile `_confinstall` target will attempt to move the files correctly from

 Of course this won't work if dhcpcd is packaged up, so packagers will need to
 install similar logic into their dhcpcd package.

 This normally happens when dhcpcd does not support the raw interface, which
 means it cannot work as a DHCP or ZeroConf client.
 Static configuration and DHCP INFORM is still allowed.
-.It Dv DUMP
-dhcpcd has been asked to dump the last lease for the interface.
 .It Dv TEST
 dhcpcd received an OFFER from a DHCP server but will not configure the
 interface.
