Instant boot Linux? (lemmy.world)

Hi all,

Is there a method out there that can "save a hibernate state" to disk, and just permanently boot immediately into that state every time?

It would be OK to lose data used after this point. And ot would also be OK if it required building a custom image based on the hardware, similar to embedded systems.

The goal is to be able to, as quickly as possible, spin up a GPU server when needed, but without using suspend/resume.

Thanks.

Baring post, my pc cold boots in 3 seconds. And does a full shutdown in 3 seconds as well.

Unfortunately my mobo's slow to post so that takes around 5-6 seconds.

I moved from arch Linux to void and its init system called runit is amazing. Mega simple and fast.

Interesting. Did you do any tuning or out of the box?

[–] fozid@lem.radiantfig.fyi 3 points 1 week ago

Out of the box. Void is a very Diy distro though, so don't expect to install it and be up and running. But I have a fully functional pc with sway / Wayland, steam and video editing, so no compromises. I was previously on arch Linux for 15 years and tuned it as hard as I could and couldn't get anywhere near this boot time.
