The solution is simple enough, drop down to the CLI and change the fstab file. The significance of that does not even need to be explained. Don't try unless you like text files. Even the graphical tool, linuxconf, is just an easy way to get to the text files, unless you are doing something really simple. Enough about the interface.
Lets go to the software distribution model.
Important programs such as X, KDE, GIMP, etc, are very difficult to install. Try installing Enlightenment on RedHat. Even using RPMS you have dozens of dependencies to go through. To make it worse, some software, like the KDE video player aKtion, call libraries by name, so if you have a newer, but still compatible version of the library with a different name, be prepared to make some symlinks. A lot of the Linux software is amateurish and not very professionally done.
