      Some distros (e.g Arch) don't have CONFIG_CHECKPOINT_RESTORE enabled by default.

  Did it change the startup time significantly?

    Yeah, it was much faster than starting up the normal way, at least for a small heap (213 ms to restore 128MB on an E5645). I didn't pursue it further because it required root (not sure if it still does) and would've required writing some kind of snapshot manager.
