It will be run by 'mkinitramfs' +# when it creates the image. It's job is to decide which files to +# install, then install them into the staging area, where the +# initramfs is being created. This happens when a new 'linux-image' +# package is installed, or when the administrator runs 'mkinitramfs' +# by hand to update an initramfs image. +# +# TODO: What about the case where you install something that should be +# added to the initramfs, but the linux-image it relates to has +# already been installed previously? Does this happen often +# enough that it needs to be handled? How can it be handled? +# +# * Think about the 'usplash'.
