This is the same problem they had with hard drive names and it seems to have been solved in a sensible way, i.e. /dev/sda still points to the first disk detected by the system, but you can look look in /dev/disk/by-path (or by-uuid, etc) to see the physical address of the devices on the system and what they are symlinked back to, and set your fstab or mdadm arrays to be configured based on those unique identifiers instead.
So, I guess what I'd like to know is why hasn't this been solved the same way? When you boot up they should present every hard wired Ethernet port as
ethX
, and the hardware address interface should be present as well but aliased back to theeth
. Then you can build the your network configs based on either one.Shouldn't be that hard right?
But nobody uses /dev/sdX anymore (not after they wipe the wrong disk once anyway). They either use logical UUIDs or hardware WWN/serial.
idk man I use /dev/sdX when running commands interactively and PARTLABELs in my
/etc/fstab
. All those letters and numbers in UUIDs are too much for my monkey brain to handle lol
