2.3. The Software Collection Root Directory

You can change the location of the root directory by setting the %_scl_prefix macro in the spec file, as in the following example:
%global _scl_prefix /opt/provider
where provider is the provider (vendor) name registered, where applicable, with the Linux Foundation and the subordinated Linux Assigned Names and Numbers Authority (LANANA), in conformance with the Filesystem Hierarchy Standard.
Each organization or project that builds and distributes Software Collections should use its own provider name, which conforms to the Filesystem Hierarchy Standard (FHS) and avoids possible conflicts between Software Collections and the base system installation.
You are advised to make the file system hierarchy conform to the following layout:
