A distribution is an organization, configuration, and ...well...distribution philosophy and set of tools to implement that philosophy. In short, a distribution is a package manager. Start with LFS, install a package manager, configure it like one of the distros, and a new identity your Linux installation will be given. We should be highlighting that the only thing really different from XFCE on Arch and XFCE on Ubuntu is the default color and icon schemes, system tray programs, and perhaps the file layout of configurations. Any comparison that differentiates totally similar distributions (Debian, Ubuntu, Mint) on equal footing with totally dissimilar distributions (Arch) glazes over the nature of the differences and obfuscates the choice of operating system. It's different strains of apples vs and orange. Please, teach your Linux taxonomy and don't exaggerate contrived identities. Linux is not soccer.
