Install and Configure mock
# dnf install mock # usermod -a -G mock <user>
Here’s how you setup a Fedora 27 x86_64 environment.
$ mock -r fedora-27-x86_64 --init $ mock -r fedora-27-x86_64 --install lorax-lmc-novirt git vim-minimal pykickstart
For a different arch or release modify the mock configuration file.
Enable network access in mock. Modify config_opts[‘rpmbuild_networking’] to True.
$ sudo vi /etc/mock/site-defaults.cfg
Kickstart files
Inside the mock chroot or container, clone the kickstarts git repository. If your system is using SELinux it needs to be set to Permissive mode while running lorax. The –old-chroot might not be needed for you. I had to use it because I had problem with loop device inside mock.
$ sudo setenforce 0 $ mock -r fedora-27-x86_64 --shell --old-chroot <mock-chroot> sh-4.4# git clone https://pagure.io/fedora-kickstarts.git
Modify the fedora-repo.ks. You’ll have to comment the rawhide repo and uncomment this line:
%include fedora-repo-not-rawhide.ks
ksflatten
change directory into fedora-kickstarts and flatten a kickstart
<mock-chroot> sh-4.4# cd fedora-kickstarts <mock-chroot> sh-4.4# ksflatten --config fedora-live-workstation.ks -oFedora-MyLiveCrypto.ks --version F27
You should see a warning about redundant “part /”, go edit the flat-fedora-live-workstation.ks and remove one of them. If you want to remove packages or group of packages, add stuff etc.. That’s where you’ll do it. For the first time I suggest you just go with the original kickstart file just to verify everything is working.

Get the iso and test it
You’ll find the iso in “/var/lib/mock/fedora-27-x86_64/root/var/lmc” just copy it somewhere else and test it using Virtualbox, kvm or qemu.
If you want to build a new iso you’ll have to delete the “/var/lmc” inside your mock, otherwise livemedia-creator won’t start.
