mer_verify_kernel_spec

#!/bin/bash

# This script verifies that the kernel HA .spec template is up to date.
#
# It's hard to keep all customer kernel HA .spec files up-to-date
# automatically This will cause kernel builds to fail (by default) or
# warn.
#
# The approach is to put a call to this script into the .spec
# template/boilerplate with a hard-coded value that corresponds to the
# version of the template. This script must be updated each time the
# .spec is updated in a way that requires a change.
#
# The .spec simply runs:
#  /usr/bin/mer_verify_kernel_spec 1 [--fatal-if-old]
#
# The script will typically examine the version passed and the version
# hard-coded in and, if it's out of date it will print a message
# (probably pointing to a web page with instructions). Depending on
# the flag the script will either exit with an error or not.
#
# The developer of course can either update the template at once, make
# it a warning only or remove the check altogether.
