Profiling ========= Installation Guides have content that depends upon the operating systems. Use separate files to specify content that is operating-system specific. Each file should have the same name but with an additional suffix. The following suffixes should be used: * ``ubuntu`` for Ubuntu * ``debian`` for Debian * ``rdo`` for Red Hat Enterprise Linux and CentOS * ``obs`` for openSUSE and SUSE Linux Enterprise .. note:: Previously, ``.. only`` directive was used to generate conditional output. This required multiple builds and has since been phased out. | This documentation, is a derivative of `RST conventions `_ by OpenStack, used under CC BY.
