Note
for older method (namely for Fedora 23) using livecd-tools (livecd-creator) visit https://fedoraproject.org/wiki/How_to_create_and_use_a_Live_CD
Note
If you simply want to burn a pre-made ISO to a disc, visit http://fedoraproject.org/en/get-fedora to download a LiveCD or LiveDVD, then see the install guide or burning how-to for further instructions.

mock
you should always do all work in mock, this will allow you to ensure that the compose environment matches the target environment
to setup a Fedora 25 x86_64 environment you would run the following
$ mock -r fedora-25-x86_64 --init $ mock -r fedora-25-x86_64 --install lorax-lmc-novirt git vim-minimal pykickstart
if you wanted a different arch or release you would use the correct mock configuration file
kickstarts
inside the mock chroot, clone the kickstarts. If your system is using SELinux it needs to be set to Permissive mode while running lorax.
$ sudo setenforce 0 $ mock -r fedora-25-x86_64 --shellsh-4.3# git clone https://pagure.io/fedora-kickstarts.git
ksflatten
change directory into fedora-kickstarts and flatten a kickstart
sh-4.3# cd fedora-kickstarts sh-4.3# ksflatten -v, --config fedora-live-soas.ks -o flat-fedora-live-soas.ks --version F25
livemedia-creator example
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-25 --iso-only --iso-name Fedora-SoaS-25-x86_64.iso --releasever 25 --title Fedora-SoaS-live --macboot
Make a remix
edit the bottom of the flat-fedora-live-soas.ks
that you produced with ksflatten (above)
in this section of the flattened.ks:
%packages
add a program (add name)
- delete a program ( put - in front)
put # in front of listed program to not install it
