[CentOS] Custom LiveCD images with CentOS8

Is it at this moment possible to build custom LiveCD images?

Are they all necessary tools available in CentOS8?

I have never done this and wonder if it is still possible for C8.

C7 stuff seems to be here: https://github.com/CentOS/sig-core-livemedia

Not quite sure if Fedora howtos can be applied here. Any hints?

Thanks,
Leon
