Seriously this completely defeats the whole point of the information in
pkg_postinst. einfo is not logged by ELOG features by default, producing the
following:
<snip>
* You have installed dhcpcd with zeroconf support.
* You have installed dhcpcd with DUID support.
* Some DHCP server implementations require a MAC address only in the
* ClientID field. These DHCP servers should be updated to be RFC
* conformant. If you cannot do this, you can revert to the old
* behaviour by using the -I '' option OR building dhcpcd with the
* vram USE flag enabled.
* GNU info directory index is up-to-date.
</snip>
The whole info about USE="zeroconf" gets lost, and half of info about
USE="-vram" as well.
