Checkpoints and save-states. How do you capture the running state of a process and restart it at a later date, without it imploding?
There are a few ways of doing this, each with their own drawbacks. I'm currently looking into DMTCP for this.

>>589803 wait has *any* os added that? Besides virtual machines, I've never seen that but always wanted it

DMTCP is user space software though.

>>589894 that's really cool so you're implementing process save states on Linux or what os

>>590179 Phantom OS is its own system (I recommend looking into it as its design is really interesting).
DMTCP though, runs on a Linux system. The cool part is that it lives in user space and saves states to files, meaning that if two machines can share file storage, a process that is checkpointed on one can be redirected on the other.
