Perhaps it is a mobile (or semi-mobile) device?  That has always been
valid for IPv4 inet devices.  Things would pause for a few seconds
(seems like 60 seconds?) but then timeout "no persistent leases,
sleeping" and dhclient would continue retrying in the background while
the boot continued.  I just tested that inet (not inet6) configuration
again.  Is that not valid for IPv6 inet6 devices?

However if "auto" is changed to "allow-hotplug" then the setup is
event driven.  In that case the boot will proceed regardless of
network connection at boot.  The dhclient will continue to retry at
the default five minute interval.  If the network device is not
required for system operation then "allow-hotplug" is probably the
better configuration over "auto" which is boot time synchronous.
