I want to know what software is installed when I pick a specific Base Environment and Additional software for Selected Environment.
I think it is possible to check this in the RHEL installation DVD:
The installation program does not show which packages are contained in the available environments. To see which packages are contained in a specific environment or add-on, see the repodata/*-comps-variant.architecture.xml file on the Red Hat Enterprise Linux Installation DVD which you are using as the installation source.
There is a <Bunch of random characters>-comps-Everything.x86_64.xml file inside. It contains the list of software for the different options in the netinstall ISO. There is a .xz zipped version in the mirror which has the same content as the unzipped one.
Could anyone confirm that this is the correct source of information?
