=== Documentation ===
* Livemedia Creator: http://weldr.io/lorax/livemedia-creator.html
* Kickstart: https://github.com/rhinstaller/pykickstart/blob/master/docs/kickstart-docs.rst
=== Setup Environment ===
==== Cloud Base/Vagrant ====
If using the cloud base or vagrant images, install the needed kernel modules:
# dnf install kernel-modules-$(uname -r)
==== Install Mock ====
You should always do all work in mock, this will allow you to ensure that the compose environment matches the target environment.


*Older posts
# dnf install mock

# usermod -a -G mock <user>

*Examples in f24 root terminal:
=== Setup Build Environment ===
===Install files===
To setup a Fedora 27 x86_64 environment use mock to setup and install tools.
*'''livemedia-creator and ksflatten are part of lorax'''

==== Get kickstarts ====
The official Fedora kickstarts are stored in [https://pagure.io/fedora-kickstarts a git repository]. The 'master' branch is for Rawhide; there are branches for each release as well. You can use a kickstart from this repository (on the correct branch for whatever release you want your live image to be) as a base. You could also take a fully flattened kickstart from [http://koji.fedoraproject.org/koji/tasks?state=closed&view=flat&method=createLiveMedia&order=-id a recent official live image compose task] as a base.


:'''You must be in the same fedora version (f24) first. This is so that packages can be installed to livecd without SELinux errors and is relabeled at boot time.'''
If you wanted a different arch or release you would use the correct mock configuration file.

==== SELinux ====
::updated 06/28/2016
If your system is using SELinux, it needs to be set to Permissive mode while running lorax.

=== Running a Compose ===
:https://pagure.io/fedora-kickstarts/tree/f24
Go into your prepared environment to do a compose.


::alternately: git clone the repo and not get each piece manually
$ mock -r fedora-27-x86_64 --shell --old-chroot --enable-network
<mock-chroot> sh-4.3#


:Kickstarts need to flattened before use:
==== Flatten a Kickstart ====
:: hit raw tab and '''save-page-as''' to a local directory (/home/(user)/Downloads/pagure/)
The official Fedora spins are composed from templates. Flattening fully resolves the templates to a valid kickstart which can be fed to livemedia-creator. After copying a base kickstart into the mock environment, you can flatten it with e.g.:


:https://pagure.io/fedora-kickstarts/blob/f24/f/fedora-live-soas.ks
<mock-chroot> sh-4.3# ksflatten --config fedora-live-soas.ks -o flat-fedora-live-soas.ks --version F27
:https://pagure.io/fedora-kickstarts/blob/f24/f/fedora-live-base.ks
:https://pagure.io/fedora-kickstarts/blob/f24/f/fedora-live-minimization.ks
:https://pagure.io/fedora-kickstarts/blob/f24/f/fedora-repo.ks

:https://pagure.io/fedora-kickstarts/blob/f24/f/fedora-soas-packages.ks


*switch root terminal to the local directory with the kickstart files (/home/(user)/Downloads/pagure/)
==== Create the Live Image ====
Run livemedia-creator with the flattened kickstart and relevant options. This creates a Sugar on a Stick live iso that also has EFI/Mac booting support.


  ksflatten -v, --config fedora-live-soas.ks -o flat-fedora-live-soas.ks --version F24

Documentation

Setup Environment

Cloud Base/Vagrant

If using the cloud base or vagrant images, install the needed kernel modules:

# dnf install kernel-modules-$(uname -r)

Install Mock

You should always do all work in mock, this will allow you to ensure that the compose environment matches the target environment.

# dnf install mock
# usermod -a -G mock <user>

Setup Build Environment

To setup a Fedora 27 x86_64 environment use mock to setup and install tools.

Init Environment

$ mock -r fedora-27-x86_64 --init
$ mock -r fedora-27-x86_64 --install lorax-lmc-novirt vim-minimal pykickstart

Get kickstarts

The official Fedora kickstarts are stored in a git repository. The 'master' branch is for Rawhide; there are branches for each release as well. You can use a kickstart from this repository (on the correct branch for whatever release you want your live image to be) as a base. You could also take a fully flattened kickstart from a recent official live image compose task as a base.

If you wanted a different arch or release you would use the correct mock configuration file.

SELinux

If your system is using SELinux, it needs to be set to Permissive mode while running lorax.

$ sudo setenforce 0

Running a Compose

Go into your prepared environment to do a compose.

$ mock -r fedora-27-x86_64 --shell --old-chroot --enable-network
<mock-chroot> sh-4.3#

Flatten a Kickstart

The official Fedora spins are composed from templates. Flattening fully resolves the templates to a valid kickstart which can be fed to livemedia-creator. After copying a base kickstart into the mock environment, you can flatten it with e.g.:

<mock-chroot> sh-4.3# ksflatten --config fedora-live-soas.ks -o flat-fedora-live-soas.ks --version F27

Create the Live Image

Run livemedia-creator with the flattened kickstart and relevant options. This creates a Sugar on a Stick live iso that also has EFI/Mac booting support.

<mock-chroot> sh-4.3# livemedia-creator --ks flat-fedora-live-soas.ks --no-virt --resultdir /var/lmc --project Fedora-soas-Live --make-iso --volid Fedora-SoaS-27 --iso-only --iso-name Fedora-SoaS-27-x86_64.iso --releasever 27 --macboot

Compose Results

The resulting images will be located in the mock chroot. Copy them somewhere outside of the mock-chroot.

$ cp /var/lib/mock/fedora-27-x86_64/root/var/lmc/*.iso $HOME

Note: The location will be different based on your mock configuration.

Cleanup

We can now safely clean up the build environment and set SELinux back to enforcing.

$ mock -r fedora-27-x86_64 --clean
$ sudo setenforce 1
