[gentoo-user] static addr in /etc/conf.d/net ignored, dhcp used. dhcpcd crashes when forced

[n952162]

My eth0/enp2s0 network adapter is configured so:

    $ cat /etc/conf.d/net

    config_enp2s0="192.168.179.20/24"

but on boot, I get a bonjour address:

    enp2s0    Link encap:Ethernet  HWaddr 48:BA:4E:29:99:9E
               inet addr:*169.254.71.117 * Bcast:169.254.255.255 
    Mask:255.255.0.0

if I restart the service immediately after boot, nothing much happens, I
still get the bonjour address.

    sudo rc-service net.enp2s0 restart

Incidently, dhcpcd is still running at this point.

But after a couple of tries:

    sudo rc-service net.enp2s0 restart

and then I get my connection:

    $ ifconfig
    enp2s0    Link encap:Ethernet  HWaddr 48:BA:4E:29:99:9E
               inet addr:*192.168.179.20* Bcast:192.168.179.255 
    Mask:255.255.255.0

And:

    $ sudo rc-service dhcpcd status
      * status: *crashed*

 From /var/log/syslog:
****

    [  260.895907] dhcpcd[6664]: segfault at 400a00000000 ip
    0000560edbf464bd sp 00007ffe06bf4f10 error 4 in
    dhcpcd[560edbf23000+46000]*

Why does dhcpcd think it can configure my interface and what's the
connection between /etc/conf.d/net and dhcpcd?
