SuperDuper: Fully Bootable Backup for MacOS
SuperDuper is the wildly acclaimed program that makes recovery painless, because it makes creating a fully bootable backup painless. Its incredibly clear, friendly interface is understandable, easy to use, and SuperDuper's built-in scheduler makes it trivial to back up automatically. It's the perfect complement to Time Machine, allowing you to store a bootable backup alongside your Time Machine volume—and it runs beautifully on your Mac!

Boot the Raspberry Pi From USB (Instructables) - - Gmail
I found this today / just now.

It DOES require an SD to do the initial boot (chain boot) but will boot the bulk of the
system from the Flash drive.

Building a NixOS image for VirtualBox - Johbo's Notes - Working on the Web
NixOS allows to easily build images of a machine configuration. This post shows in an example how to build a more recent version of the base image which NixOPS uses to spin off Virtualbox based machines. The idea should be applicable to all kinds of machine configurations.

Rethinking PID 1
For a fast and efficient boot-up two things are crucial:

To start less.
And to start more in parallel.
What does that mean? Starting less means starting fewer services or deferring the starting of services until they are actually needed. There are some services where we know that they will be required sooner or later (syslog, D-Bus system bus, etc.), but for many others this isn't the case. For example, bluetoothd does not need to be running unless a bluetooth dongle is actually plugged in or an application wants to talk to its D-Bus interfaces. Same for a printing system: unless the machine physically is connected to a printer, or an application wants to print something, there is no need to run a printing daemon such as CUPS. Avahi: if the machine is not connected to a network, there is no need to run Avahi, unless some application wants to use its APIs. And even SSH: as long as nobody wants to contact your machine there is no need to run it, as long as it is then started on the first connection. (And admit it, on most machines where sshd might be listening somebody connects to it only every other month or so.)

Starting more in parallel means that if we have to run something, we should not serialize its start-up (as sysvinit does), but run it all at the same time, so that the available CPU and disk IO bandwidth is maxed out, and hence the overall start-up time minimized.
