dhcpcd-discuss

Hi,

Over at Artix Linux, we recently upgraded dhcpcd from 9.2.0 to 9.3.1 and
started receiving reports from users that their network connection no
longer works (happened to myself as well actually). I did a little bit
of testing myself and found 9.3.0 had the same issue. The logs we get
from dhcpcd looks something like:

>2020-10-28 11:32:40.049433743  dhcpcd-9.3.1 starting

>2020-10-28 11:32:40.058365491  dev: loaded udev

It appears that the dhcpcd master process doesn't get launched and thus,
no network connection. This so far only appears to affect a subset of
users. Not sure if this is a total coincidence or not but everyone that
has reported this uses ipv6 thus far... Any pointers would be
appreciated.

Thanks!
