Architecture: x86_64
Machine: amd64
>Description:
1. dhcpcd adds an alias address if one is already set for IPv4. There should
be an option to override the primary address like dhclient does.
2. something leaves behind network routes created for the interface when
dhcpcd is killed. It should cleanup, because when moving between different
networks makes one unreachable from another.
>How-To-Repeat:
start dhclient, get address, kill it. change to different network
(with different ip address). In the wireless world join net with different
ssid.
start dhcpcd...
>Fix:
1. add configuration option to override the primary address instead of creating
aliases.
2. figure out what adds the route, and remove it.

I've added to noalias dhcpcd.conf directive to dhcpcd trunk here:

Now, perhaps one shouldn't stop dhcpcd(8) with a SIGTERM, but it still
should DTRT if you do.

Update of /cvsroot/src/external/bsd/dhcpcd/dist
In directory ivanova.netbsd.org:/tmp/cvs-serv6066
Log Message:
Import dhcpcd-6.0.0 with the following changes:
* DHCPv6 support
* wpa_supplicant hook script
* route IPv4 addresses to 127.0.0.1 for machine centric traffic
* DHCPv6 Prefix Delegation support
* DHCPv6 FQDN support
* Control existing IPv4 routes
* less spamy to syslog by default
* IPv6 protocols now wait for a valid LL address before starting
* IPv6 DAD support now listens to kernel for more accurate timings
* IPv4 code split out more cleanly so dhcpcd can be compiled for
IPv4, IPv6 or IPv4 AND IPv6
* MTU is no longer requested by default
* a DUID is now generated in /etc/dhcpcd.duid and this is used as a
client ID for DHCPv4 and DHCPv6
This does mean that you may get new DHCPv4 addresses
Many bugs have also been fixed along the way and this release addresses

dhcpcd-6.6.4 has been imported now which addresses these concerns in a
different vein by reloading the last lease if the IP address for it
still exists on the interface.
All options contained within the lease such as address, routing, etc are
cleaned up if needed when dhcpcd receives an event from the DHCP server
or times out.
To get dhcpcd to remove everything at SIGTERM, simply remove the
persistent option from the default dhcpcd.conf file in /etc
