[eudev] Plans to adopt persistent network device naming?

[Daniel Campbell]

udev recently hit v197, and with it a system that changes the way
network devices are detected and assigned symlinks. Instead of eth0,
eth1, etc. and wlan0, wlan1, etc, it uses strange names for devices. [1]

As a user who switched to Gentoo to avoid the systemd cancer, I'm
concerned about what eudev's position is on this change. Is it a change
that will be pursued, a mere opt-in option, or will this not ever appear?

Personally I see little reason to adopt this. It'd be best to not have
it at all, but if it's going to be in eudev, it'd probably be best to
make it opt-in instead of udev's opt-out.

So what's the verdict?

We have not discussed this as a team, but I'm going to venture a guess 
given our general outlook.  We will support both schemes and probably go 
with the conservative must-opt-in approach.  I have yet to see what 
implementation details are needed for the predictable network interface 
name.  Its possible that the opt-in/opt-out question may not even be 
relevant if we can autodetect a system configured for one approach over 
another.

I'm all for new features that may be useful, but not at the expense of 
forcing users to needlessly reconfigure systems.
