You are right, there are several different ways to disable udev's
predictable network interface names:

1) add net.ifnames=0 to the kernel command line in your boot loader
configuration.

2) use any of the methods listed on the upstream wiki [1] under "I don't
like this, how do I disable this?"

None of those should cause problems later.
