38# This approach assumes that the microcode binaries are properly padded, and
39# their headers specify the correct size. This works fairly well on isolatied
40# updates, such as Intel and some AMD microcode, but won't work very well if the
41# updates are wrapped in a container, like AMD's microcode update container. If
42# there is only one microcode binary (i.e. one container), then we don't have
43# this issue, and this rule will continue to work.
