One would assume that "saving it to a disk" is simply a degenerate case of migrating the process... Presuming they have process migration working (and it seemed close a while ago when I last looked), saving to a file might already be supported... I'd google "process migration" and you are likely to find a lot of discussion on this topic... /mike >- >To unsubscribe from this list: send the line "unsubscribe linux-kernel" in >the body of a message to majordomo@vger.kernel.org >More majordomo info at http://vger.kernel.org/majordomo-info.html >Please read the FAQ at http://www.tux.org/lkml/ > > > - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
