I call them unrecognisable because they are hard to recognise, as in hard to read and impossible to remember. I find that annoying. I can call them "annoying names" if you prefer that :) > There is nothing wrong with wanting things to work as you do, but it > requires input to do so.

A configuration file assigning editable names to the annoying names could be created automatically and filled by assigning the name an interface already has to it (because when it has a name, the name is known, which is easier than trying to make up all possible names in advance). Then only if you wanted you would edit the configuration file to assign the name(s) of your choosing, and if you don't want to do that, you simply get the names you get now. There would be no change to how the names are now, only an additional option. That would also have the advantage that when the annoying name of an interface changes, you can choose to either adjust all configuration files in which you have specified a particular interface or simply adjust the one configuration file that assigns the names. I actually wonder why they didn't virtualise the names. It makes too much sense for not to do it, and you could do likewise with other devices (especially disks).
