It might be a waste of time or it might be a good idea, you decide. A short description would be "continuous system hibernation". Say you are running Firefox, writing an e-mail in mutt and compiling the next X.org release. The power goes off, your computer crashes or something happens and you lose everything you were doing (yes, sadly you haved saved your e-mail as a draft yet). The "continuous hibernation" is some kind of memory snapshots taken, say, every 5 minutes. The next time your system starts after a crash, it'd say "oh oh, looks like something went wrong" and offer you a list of the last N (for instance, 4) snapshots and you can recover your system to the very same state it was before power went off or your dog unplugged your CPU. It might even ask you which individual applications you want to start from that snapshot: maybe you don't want to start Quake 3. Provided the implementation is fast enough and you have a large hard drive, it might even allow you to say: "I want to restore the system to the same stage it had on Monday, 11.04PM" That's it. Please, shoot at the idea not at the idealist :-) - -- Pau Garcia i Quiles http://www.elpauer.org (Due to the amount of work, I usually need 10 days to answer) -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQFEcMAj/DzYv9iGJzsRAnO9AKDwoybV6sdmPHmxe6poTTReW3ldOgCgr7jb Qt47QlO6BVG14+o7rODhoNI= =zoTu -----END PGP SIGNATURE----- - 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/
