I am thinking of trying ‘Fedora Everything Netinst’ for custom install but can’t seems to find detailed information about available additional packages (on the right side of installer screen). Is there any page where the information about different options is available? e.g the option in KDE Multimedia or KDE Application does not give a clue which specific applications this option is going to install.
While each item may not give the fine details from the installer you can be assured that all the appropriate (and necessary) packages to support that chosen item will be included.
Although I do not know how, it seems likely someone may be able to suggest a means of getting the finer details for each option there.
