# kmodtool - Helper script for building kernel module RPMs
|
|
# An original version appeared in Fedora. This version is
|
|
# generally called only by the %kernel_module_package RPM macro
|
|
# during the process of building Driver Update Packages (which
|
|
# are also known as "kmods" in the Fedora community).

# Changelog:
|
|
#
|
|
# 2010/07/28 - Add fixes for filelists in line with LF standard
|
|
# - Remove now defunct "framepointer" kernel variant
|
|
# - Change version to "rhel6-rh2" as a consequence.
|
|
#
|
|
# 2010/01/10 - Simplified for RHEL6. We are working on upstream
|
|
# moving to a newer format and in any case do not
|
|
# need to retain support for really old systems.
