I delete the udev rules that implements this on all my server images, it's just not needed. If an interface fails badly enough that other interfaces get renamed to fill the gap, things don't work (it doesn't cause a security risk as the IPs and routes won't be able to make connections any longer
> The better solution is to stay with an init system that works well and doesn't get in our way and doesn't cause random problems by starting services in a different order on every boot.
On my laptop, I like a fast booting system, but I've been able to do that for a decade by stripping down the boot process to not try a bunch of stuff that I don't need.
On servers, predictability and stability are far more important than boot speed. Boot speed is limited by the hardware initialization anyway, I've got large systems that take so long to go through the hardware initialization that I can hit power on one of the large system at the same time I do on a simple (but fast) system, and boot the simple system off a CD, install the OS, and move the CD to the complex system before it gets around to reading the CD. I've setup demos of doing exactly this to impress manager types about how fast the install process is :-)
If you want a fast boot and don't have to dig into the boot process when something goes wrong, the newer init systems are nice.
But if boot speed is not that important to you, but predictability is, then async device detection, parallelizing the boot, etc add complexity and race conditions that cause more harm than the benefit provided.
