# We push the image to hub twice, once with the full kernel version of
# "mobylinux/kernel:<kernel version>.<major version>.<minor version>-<n>",
# where "<n>" is a monotonically increasing config number, and as
# "mobylinux/kernel:<kernel version>.<major version>.x". This version
# number is stored in IMAGE_VERSION.
#
# We expect most users to us the "<kernel version>.<major version>.x"
# variant as this simply is the latest version of a given major kernel
# version. This version number is stored in IMAGE_MAJOR_VERSION.
#
# For IMAGE_VERSION, the "<n>" must be increased whenever
# the kernel config or the patches change. We don't expect this to
# happen very often as the minor version number gets update quite
# frequently.
#
# IMAGE_VERSION is used to determine if a new image should be pushed to hub.
