I am posting a quick cookbook on creating hanlon microkernel for easy reference. Detailed information on how the microkernel organized and build along with details on each of the command listed here can be found on git hanlon microkernel wiki1. Install dependenciessudo apt-get install squashfs-tools -y
sudo apt-get install -y fakeroot
sudo apt-get install p7zip-full -y
sudo apt-get install curl -y2. Install Ruby (I prefer using rvm)\curl -sSL https://get.rvm.io | bash -s stable --ruby
source /home/user/.rvm/scripts/rvm3. Clone hanlon micro-kernel project into your working directory (my directory ~/wspace/hanlon/hanlon-mk)cd
mkdir wspace
mkdir hanlon
git clone hanlon-mk
cd hanlon-mk4. Clone hanlon micro-kernel project into your working directory (my directory ~/wspace/hanlon/hanlon-mk)cd
mkdir wspace
mkdir hanlon
git clone hanlon-mk5. Create bundle file: This would create a temporary tar file containing all necessary files to complete iso creation processcd hanlon-mk
