Building kernel 3.6.1 on RHEL6, notes.

yum -y install gcc make

# we first need newer module-init-tools.
# Using the module-init-tools-3.9-20 from rhel6 leads to 'depmod' beeing aborted with 'Killed'.
# For installation of the newer module-init-tools we need glibc-static from optional channel.
rhn_register 
rhn-channel -a -c rhel-x86_64-server-optional-6
yum install glibc-static docbook-utils

# fetch module init tools from https://modules.wiki.kernel.org/index.php/Main_Page
