-# Debian with PREEMPT_RT patched kernel
-## Overview
-Theses short steps were tested on Debian Wheezy 7.4, x64 core.
-## Steps
-Create a "workspace", where you have some free disk space
-    mkdir ~/rt_kern
-    cd ~/rt_kern
-Get the files !
-    wget -c https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.14.25.tar.xz
-    wget -c https://www.kernel.org/pub/linux/kernel/projects/rt/3.14/patch-3.14.25-rt22.patch.xz
-Extract and patch
-    tar xaf linux-3.14.25.tar.xz
-    unxz patch-3.14.25-rt22.patch.xz
-    cd ./linux-3.14.25
-    patch -p1 < ../patch-3.14.25-rt22.patch
-Get the config of your current Debian kernel
-    cp -vf /boot/config-3.2.0-4-amd64 .config
-Now comes the _fun_ part: __Configuring the Kernel__ That's usually the part where you screw up and build a non-working kernel.
-    make menuconfig
-Note: I missed some libraries so be able to run this command, you probably do too.
-   sudo aptitude install libncurses5-dev
-Once you get the configuration GUI, you have to select a few options:
-* Enable the full RT features: `Processor type and features  > Preemption Model > (Fully Preemptible Kernel (RT))`
-Save and quit (TAB until you can select the option)
-Build (where X is two times the number of cores of your CPU). Took 45minutes on my 2.5Ghz Core2Duo, with SSD.
-    make -jX
-Or, you can directly build the debian packages:
-    make deb-pkg LOCALVERSION=-hyde KDEB_PKGVERSION=1
-Install it
-    cd ../
-    sudo dpkg -i ./linux-image-3.14.25-rt22-hyde_1_amd64.deb
-Aaannndd reboot, select your new kernel =)
