Very cool. Could this improve boot times?

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

It depends on what your bottleneck is. For example on my system I get
$ systemd-analyze
Startup finished in 11.976s (firmware) + 3.879s (loader) + 2.013s (kernel) + 157ms (initrd) + 6.354s (userspace) = 24.382s
graphical.target reached after 6.316s in userspace.
The kernel boot process is only responsible for 2s of my boot time. So even if this does end up improving boot times, there's very little it can do. The real improvement for me would be to choose a faster-booting m/b. You can run systemd-analyze on your setup to see if the kernel boot time is more significant for you.
Well the aim is to sanitize the code and move some of the unnecessary boot procedures to a later stage of start up. I don't think boot times differences would be noticable.
