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.

Linux boots pretty quick

I never managed to make linux boot faster than windows (on the same device ofc).

And to this day I don't understand why.

Out of the 3 desktop OSes (lin, win, mac) linux was always the slowest one in my experience.

Fast boot most likely. Windows can shut down user processes and then hibernate the kernel/system processes. Because the system only changes on updates, it doesn't have to wrote the hibernate file every time, only on update. Never understood why distros didn't look to replicate that. If they had this would probably be a non-issue for me.
