Building an ISO

Instructions (Windows)

  1. Enable Hyper-V.
  2. Make sure you have QEMU installed. A 64-bit Windows QEMU installer can be downloaded from here. Use the default installation path for QEMU.
  3. Open a PowerShell window with Administrator privileges.
  4. Run build-iso.ps1.

Instructions (Linux)

  1. Make sure you have the commands: qemu-img, qemu-nbd, qemu-system-x86_64, partprobe, modprobe, sed, wc, xorriso, git, make, curl, and cc.

Here are commands to install these packages on various distros:

  • Ubuntu
sudo apt install qemu-utils qemu-system-x86 qemu-system-gui parted kmod xorriso sed coreutils git make curl build-essential gcc
  • Fedora
sudo dnf install qemu-img qemu-system-x86 parted kmod sed coreutils xorriso git make curl gcc
  1. Run build-iso.sh.

Details

The script will generate a Distro ISO. It may take a minute or two. The build script uses an automatic minimal install ISO to bootstrap a temporary virtual machine, copy over the contents of the repository to this VM, and then perform an auto-build process. During this process it reboots a few times, recompiles the Kernel, and then builds a Distro ISO. After the Distro ISO is built, the VM will power-off, and the Distro ISO will be copied off the temporary VM. The resulting ISO will be located in the build folder.

Troubleshooting

If the build-iso script doesn't work, there are a few options. If you happen to have an existing VM, you could use the sync script to copy the repo contents directly over a VM's HDD. If the build process hangs immediately at Copying to Distro/, a fresh clone of the repo may fix it.
