As a restructure, nothing is changed from the original behaviour and
naming despite the file structure changing. The symlinks to build had
to be updated generating lots of "deleted" and "new_file".
The new structure is:
docker/${base_distro}/${type}/${container}
base_distro == centos, ubuntu, fedora, etc
type == source, binary, rdo
type rdo is a symlink to binary for backwards compatibility
Two new flags are added to the build-all script to support the ability
to support different base distros and a flag to support binary or source
containers.
There are several added folders that are empty to hold the directory
structure for future containers of these types.
To use a prefix other than centos-rdo- you can set PREFIX in the toplevel
directory .buildconf file
