As a follow up to that, a tweet from Colin
(https://twitter.com/cperciva/status/1444910673893355525) a few hours
ago says
"Loader and kernel are around 2.7 seconds now.
There's a breakdown of that time on the wiki:
https://wiki.freebsd.org/BootTime"
That's on an AWS c5.xlarge instance which he's using as a standard. I'm
looking forward to seeing this work appearing in RELEASE in the future.
