Yes. But... I don't like changing boot parameters for this (it means the 
sanity of my system is now wholly dependent on my bootloader's 
configuration file, which is a dependency I do not want to have; any 
form of alternative booting of the kernel now *also* needs to reference 
those parameters for the system to keep functioning as normal (if it 
uses any firewall scripts or the like) which is something I don't want 
and don't want to invest in.

It should be purely based on on-disk structures that either just belong 
to /etc, (preferably) or get added to the initrd.

The udev rule is convenient enough except that udev is incomprehensible 
so the only way to manage this is to keep a notition of this in some 
convenient internet location of your own because invariably you are 
going to lose access to wherever you have stored it, and you can't 
memorize this or produce it from memory.

Meaning, unless you have some trustworthy access to this information you 
will not be able to reproduce it when you configure a new system and you 
will just forget and not care.

Which seems to be the intent of the designers: that it is so hard or 
inconvenient that most people just won't bother and use the default.

Hence, more people using what they want.

I believe the way to turn off the system is to do:

ln -s /dev/null /etc/udev/rules.d/70-persistent-net.rules

Which I did in the beginning but I can never remember the name.

At a certain point I fixed my static IP in a central dnsmasq config file 
so my static IPs are getting fixed through DHCP but before I definitely 
didn't have this facility and simply preferred to use 
/etc/network/interfaces which became hideous under this system.

I still don't like seeing this enp4s0 (under the previous motherboard it 
was enp3s0, go figure) whenever I look under the hood and detest it to 
the bone.

It is like calling a house in a street with no other houses, house 
number 2530.

2530 Empty Street.

Why 2530? Well, the hash of the number of bricks used to built the house 
was 2530, that's why.

Makes sense right. right. Maybe I will use this thread to find this 
information ;-).
