[gentoo-user] udev-197: activate new naming scheme

[Grant]

I've booted into udev-197 but my network interfaces are named the same
as ever and I've read that the new naming scheme is deactivated by
default.  Do you think the new naming scheme will stick?  If so, how
can I activate it?

In the discussion in [1] the consensus seems to be that they actually
solve a real problem, and that they are an improvement to the old
scheme.

Follow the instructions at [2]. In short, eliminate
/etc/udev/rules.d/80-net-name-slot.rules and
/etc/udev/rules.d/70-persistent-net.rules.

While I am fiddling around with systemd that is the perfect time to also
try this one. Switched to the new scheme on two of my systems, no
problems so far.

What helped:

on the thinkpad I use networkmanager so I didn't have to do anything ...

I assume openrc-users would have to relink net.lo to the new names like
net.enp6s0 in my case (instead of the old net.eth0)?

-

On the other machine with systemd I only had to edit my funny
kvm-bridge.service to match the new NIC-device.

Runs fine.

In general I see the benefit in this new approach even when it means to
let old habits go somehow. Well, we have the option to keep the good old
naming by just setting/keeping the old udev-rules.

Thank you for the info.  I just read the contents of the above file
which has good info too.
