%description
Hibernating Agent for Linux on Amazon EC2

This agent does several things:

1. Upon startup it checks for sufficient swap space to allow hibernate
   and fails if it's present but there's not enough of it.
2. If there's no swap space, it creates it and launches a background
   thread to touch all of its blocks to make sure that EBS volumes
   are pre-warmed.
3. It updates the offset of the swap file in the kernel using
   SNAPSHOT_SET_SWAP_AREA ioctl.
4. It daemonizes and starts a polling thread to listen for instance
   termination notifications.
