How to build the official style iso image?

/usr/share/clr-installer is created and populated by the build process for clr-installer itself. For the ISO templates, for example, see:

You can see the files populated during packaging here:

The installer configs and scripts for the current release are always published here:
https://download.clearlinux.org/current/config/image/

So, in summary:

  1. Download and build clr-installer from source (or add the clr-installer bundle if you’re already running Clear Linux).
  2. Download the contents of /current/config/image.
  3. Run clr-installer -c live-server.yaml

That’s all you need to replicate our official builds.
