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

$ sudo setenforce 0
$ mock -r fedora-25-x86_64 --shell
<mock-chroot> sh-4.3# git clone https://pagure.io/fedora-kickstarts.git

ksflatten

change directory into fedora-kickstarts and flatten a kickstart

<mock-chroot> sh-4.3# cd fedora-kickstarts
<mock-chroot> sh-4.3# ksflatten -v, --config fedora-live-soas.ks -o flat-fedora-live-soas.ks --version F25

livemedia-creator example

<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-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
