Yes, kill (remove) 75-persistent-net-generator.rules when building your

I do that at build-time. For reference, I'm using this script:
| #!/bin/sh -e

| # Since udev may remember the different interfaces on every node, one
| # can then notice the use of eth0, eth1, eth2, etc., which will break
| # the initramfs. To work around this, it's been chosen to disable the
| # following udev rule file, so that there's no net device persistence.
| NASTY_SCRIPT_PATTERN='*persistent-net-generator.rules'

| # Previously, an rm call was used, but since the script got moved to
| # its own symlink under /etc/udev/rules.d, it's been chosen to use a
| # find call instead, removing the script and its symlinks, both in the
| # old and new udev cases.

| # For reference, the upload which introduced this move is 0.124-1

Given it's trivial, you can consider it “released” under those terms:
