I changed a Gentoo hard disk to a different laptop and I lost internet connectivity.
What likely happened? How can I resolve. I can't post any commands as I have no connectivity
Ip link shows lo, enp0s31f6, and sit0@none. Ifconfig shows enp0s31f6 and lo

If you were using networkmanager, it should just work.

But likely if you switched to completely different hardware and were just using openrc to configure the network, the configuration script in /etc/init.d/net.$IFACE (where $IFACE=enp0s31f6) is not there, and the old computer's interface is still there.

I believe I am using openrc to configure the network.

Looking at /etc/init.d I see net-online, net.eth0 and net.lo. which is likely to be the old machines file? Can it just be deleted and then restart?

Need to change that net.eth0 symlink to net.enp0s31f6, or create a new one pointing to the same place so it could boot on either machine but give a warning on missing network interfaces.

As a reminder https://wiki.gentoo.org/wiki/Handbook:AMD64/Networking/Modular -- but it sounds like you inherited the disk?

You'll also need to edit /etc/conf.d/net to use the new interface name.

Is it too hacky to write two udev rules to rename the two interfaces two the same thing, using MAC address matching.
It would be a horrible mess if both interfaces were in the same system at the same time.
