• Warning this is a very unstable test set of builds Do not use except for testing
• 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

• 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.

• Examples in f25 root terminal:

Install files

• livemedia-creator and ksflatten are part of lorax

# dnf install lorax virt-install libvirt-daemon-config-network pykickstart

                                                                                                                                               

• Must be done first:

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.

Notes

"In --no-virt mode it's calling anaconda
directly so kickstart processing of the %include may work, depending on
the location of the files. But if you're using it in virt mode only the
top level ks gets passed into the vm so ksflatten is required in that
case."

alternately: git clone the repo and not get each piece manually

Kickstarts need to flattened before use:

hit raw tab and save-page-as to a local directory (/home/(user)/Downloads/pagure/)

• switch root terminal to the local directory with the kickstart files (/home/(user)/Downloads/pagure/)

ksflatten

updated 06/28/2016

ksflatten -v, --config fedora-live-soas.ks -o flat-fedora-live-soas.ks --version F25

livemedia-creator example

livemedia-creator --ks /home/(user)/Downloads/pagure/flat-fedora-live-soas.ks --no-virt --resultdir /home/(user)/lmc/Downloads/ --project Fedora-soas-Live --make-iso --volid Fedora-SoaS-flat-live --iso-only --iso-name Fedora-SoaS-flat-live.iso --releasever 25 --title Fedora-SoaS-flat-live --macboot

note the changes from f24

not in /tmp/lmc

Make a remix

• edit the bottom of the flat-fedora-live-soas.ks

that you produce 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

Build takes a long time wait for completion

ends with:
