I've been upgrading my machines Bullseye => Bookworm recently. In a few of these
upgrades, the name of the ethernet device changed. (E.g. enP2p32s15f0 =>
enP2p0s15f0) This required changes to /etc/network/interfaces in order to start up
the interface.
This is only a minor inconvenience (though it may require me to take a drive
out 30 miles to the location where a few of these machines reside -- no
problem, it's a beautiful drive!)
However, I seem to remember that once upon a time there was a way to get (I think it
involved udev) the system to assign an arbitrary name (e.g. (enet0") to a given
interface based on something that doesn't change when the firmware/driver gets
upgraded. For example, the MAC address for an Ethernet interface would be a good
basis.
The trouble is that it was a while ago and I can't remember how to do that?
Any hints will be appreciated. Pointers to documentation on the subject would
be especially helpful!
systemd.link should be a way to get this done:
