 In common with other operating systems , OpenBSD provides a package management system for easy installation and management of programs which are not part of the base operating system . Packages are binary files which are extracted , managed and removed using the package tools . On OpenBSD , the source of packages is the ports system , a collection of <unk> and other infrastructure required to create packages . In OpenBSD , the ports and base operating system are developed and released together for each version : this means that the ports or packages released with , for example , 4 @.@ 6 are not suitable for use with 4 @.@ 5 and vice versa .
