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.

Desktop woth GPUs. I've tried immutable, but that really doesn't impact boot speed. It's still the same startup procedure. And I use ZFS, so I could roll back (or use tmpfs), but that still requires the full boot process.

What's your use case or broader goal? In some specific cases you might be able to use a VM instead of a bare metal server. The host would be idling all the time, but the VM can start from a snapshot near instantly
