Ima dodatna tri repoa Addons, Computational i Unsupported
Da bi ste ih aktivirali potrebno je da instalirate puias-addons, puias-computational i puias-unsupported pakete.
The Addons repository contains additional packages not included in a stock Red Hat distribution. The Computational repository also includes additional packages, however, these packages are specific to scientific computing. The Unsupported repository is a place where one time packages are put, they are unsupported and may change frequently.
