> From the product perspective, booting another instance (say I have Ubuntu 22.04 and 18.04 both available) in ~ 1 second, can be seen, and even proved with some A/B testing, as a huge advantage. For me at least, they went to more trouble than it's worth for that ~6-7 second gain, given that a normal systemd distro will boot in 7 or 8 seconds anyway. Maybe the difference is bigger on spinning rust. But when I used WSL regularly I was in one VM all day every day. It was always running, so I really wasn't worried about the 10 seconds it took to start up or whatever. At the same time, their custom init setup caused compatibility issues with my distro of choice and some applications (somehow). So it didn't come for free.
