This is way more complex than what you need, edit away.  I've never
observed this to fail.  I avoid UEFI boot unless it's unavoidable.

I've never observed it to fail, and I use it to build EC2 instances where I
have no console access.  It might seem that there are a lot of partitions,
but I build security appliances.
