## Configure and make kernel
## https://en.wikibooks.org/wiki/Grsecurity/Configuring_and_Installing_grsecurity
##
## Note: for configuration and installing, additional packages are required. On debian 8 you can use the following:
## eg. apt-get update && apt-get install kernel-common linux-headers-amd64 gcc make libncurses5-dev fakeroot gcc-4.9-plugin-dev dpkg-dev
##
#tar -xf $KERNEL
#cd linux-*
#patch -p1 < ../$GRSEC
#
#
#echo '''
#Now we need to configure the kernel. Note the following:
# - You need to turn on "grsecurity" in "Security" menu.
# - You can use the automatic configuration of grsec (options are server and desktop).
# - When ready, press enter'''
#read
#
#make menuconfig
#export CONCURRENCY_LEVEL=3 # Assuming you want to compile with 2 cores.
#fakeroot make deb-pkg -j 3 # Assuming you want to compile with 2 cores. If you have more, change the value of -j.
#
#
## RBAC
#cd ..
#tar xzf $GRADM
#cd gradm
#
#echo "Now you can run the make command."
#
## make # with non-root user or use the next command to make it work.
##make nopam # without pam support
#
##make install
#
## In case of problem with shutdown subject: just comment the line out in rbac config. At least that worked last time.
