# Class: base::swap
#
# This class manages swapspace on a node.
#
# Parameters:
# - $ensure Allows creation or removal of swapspace and the corresponding file.
# - $swapfile Defaults to /mnt which is a fast ephemeral filesystem on EC2 instances.
#             This keeps performance reasonable while avoiding I/O charges on EBS.
# - $swapfilesize Size of the swapfile in MB. Defaults to memory size, but see Requires.
