+# 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.
