Create LiveCD

Generation of a Atomic LiveCD for use with Minishift

[gbraad]

Hi @cgwalters @rvykydal, at the moment I am trying to use livemedia-creator to generate a livecd image with CentOS Atomic. I run it on F25 and using the following files: https://gist.github.com/gbraad/a816bf7dd1d361473eff54a5b0d6d2ca For some reason it fails. I would also prefer to run it without --no-virt but it wants me to use an installer image... which one?

[cgwalters]

I'd need to refresh my memory on the toolchain here to help debug this. Offhand for the setfiles error, presumably it's running that from the host system? Do you not have policycoreutils?

[gbraad]

Wasn't there for the python bindings: just did dnf install -y policycoreutils-python. re-running...

The setfiles issue disappeared now, but now fails even during the ostree pull:

@dustymabe any updates for Atomic to allow LiveCD creation?

[Conan-Kudo]

I'd love to be able to create live media based on RPM-OSTree, particularly something like the Atomic Workstation or similar.

Not sure if this is the right place to mention my particular desire to be able to do this, but @gbraad asked me to, so here I am.

[gbraad]

@dustymabe should we discuss this further on pagure? as the usecase from @Conan-Kudo is also a very valid one.

[dustymabe]

yes, we should discuss this further on pagure: https://pagure.io/atomic-wg/issue/289
