Well, yeah, thanks. Of course, that was the first thing I tried... and
it does start the interface.

From /etc/conf.d/net:
,----
| # config_eth0="192.168.1.22 netmask 255.255.255.0 brd 192.168.1.255"
| # routes_eth0="default via 192.168.1.1"
| 
| config_enp0s3="192.168.1.22/24"
| routes_enp0s3="default via 192.168.1.1"
`----

However any attempt to start sshd tries to
call eth0 instead of enp0s3.

But I finally discovered I still had an net.eth0 in
/etc/init.d... once I removed that, leaving only net.enp0s3... it all
began to work... Thanks again.

Thanks, good to know, and I saw that while googling too, but kind of
figured it would just be postponing the changes

Still though, doesn't it seem like the 'Quick Installation' document
and for that matter, the Handbook... should be edited to reflect this
major change... even if it was just adding a url that explains how to
work with the new stuff?

Is there a single document somewhere that explains what this is all
about and how to configure for it?  Well, yes there is.

There was a document from eselect news about it... 

During install it was 'eselect news read 4'

I read it but didn't really get what changes needed to happen.. now
looking back at that document it's hard to see how I could fail to
understand, as it is pretty insistent about how your system will be
fudge if you don't pay attention.

I guess those old ethX names are so deeply ingrained... blah
blah. excuse, excuse ... 4 flat tires, ... hit by comet .. blah
abducted... rear end probed...blah, etc etc.

[gentoo-user] Where to find the straight dope conf.d/net?

[Harry Putnam]

I was off gentoo for a few mnths... apparently something has changed
in the naming of the network devices.

So far I've read several accounts of it... but the install handbook
has apparently not been brought up to date.

Doing a fresh install, and following the contents of the manual
concerning conf.d/net... is not working, of course.

Renaming the device in /etc/init.d to net.enp0s3 and using that name
in conf.d/net doesn't work either.  At least not during boot.

I can start the network by hand with /etc/init.d/net.enp0s3 start

No problems there.  But what, exactly, is supposed to go in
conf.d/net?

I've found quite a lot of confusing information on google but not a
solution that works for me.

If I start the network by hand as above then things like sshd blow up
from trying to restart them again and using the wrong names.

Can someone point me to concise documentation about how this new setup
is supposed to work?

In /etc/conf.d/net you should replace the previously named eth0 directives to 
your new NIC name, e.g. instead of:

  config_eth0="dhcp"

you will use the new name:

  config_enp0s3="dhcp"

and so on.  For more details on the parameters used look at:

/usr/share/doc/openrc-0.11.8/net.example.bz2

Or add net.ifnames=0 to your kernel boot options to keep the old naming
style.
