I am running a server for our research group, and in charge of it, since I'm the main user.
I want to be able to (First) restart the server, while keeping some processes in their running state (runs can take weeks and killing them costs a lot of run time sometimes).
The problem is that I wish also to update the computer (and kernel) occasionally, which means hibernation is not sufficient.
What I'm looking for is a software that "freezes" a process to disk, then revives it after reboot, preferably (of course) in a newer kernel.
I foud the program called cryopid (http://cryopid.berlios.de/
) that claims to do so but doesn't compile, and is quite old.
Do you know anything like that? I also looked at (and installed) tuxonice, but it doesn't seem to have this feature.
