 Some BSD systems protect against IPv6 NS/NA messages by ensuring that the
-source address matches an address/prefix on the interface.
-This is an error as the correct check is for on-link prefixes.
-As such, on these systems stateful addressing via DHCPv6 may cause issues

 We try and detect how dhcpcd should interact with system services at runtime.
 If we cannot auto-detect how do to this, or it is wrong then
