The purpose of this agent is to create a setup for an instance to support hibernation feature. The setup is created only on supported instance types. Upon startup, it checks for sufficient swap space to allow hibernate and fails if it's present but there's not enough of it. If there's no swap space, it launches a background thread to create it and touch all of its blocks to make sure that EBS volumes are pre-warmed if configured. This is configurable. It updates the offset of the swap file in the kernel using SNAPSHOT_SET_SWAP_AREA ioctl. It updates the resume offset and resume device in grub file.
