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.

Just for the record, Linux can do with less swap-space than the memory you have, also for hibernation. The system doesn't write every byte to swap, and it uses compression. With 32gb I would choose a default swapsize of ~10gb max, but test it first as it depends on the specific content of your ram, and usage patterns oc. However, its an instant time-saver during boot.
