Sidenote, something is really wrong with your hardware or configuration
if it takes 5 seconds to get to userspace on a modern system these days.
Everything[1] I run is in the sub-second boot time before userspace is
hit, and everything boots to full graphics mode in less than 5 seconds.
The long-pole is by far, the bios/uefi these days.

I think you need new hardware, or a better kernel .config file :)

That would be great, thanks for doing this.

this isn't just new hardware by any means.
