PC-BSD Installer is the installation program for PC-BSD (PCBSD) that is a Unix-like, desktop-oriented operating system built upon the latest releases of FreeBSD. The Installer can be installed through a click-and-point program that guides the user from the desktop environment selection to the basic and advanced disk set-up procedures. In the basic and advanced disk set-up, the user is instructed to select the disk or partition to be installed. There are four desktop environments to choose from – KDE (K Desktop Environment), GNOME, LXDE and Xfce. After installation of the Installer, PC-BSD can be installed and may be used immediately if KDE SC is provided as the pre-installed graphical user interface. The KDE is a full-featured desktop environment that includes support for multiple desktops, 3D desktop effects, and a variety of built-in tools and utilities for both new and power-desktop users. PC-BSD supports ZFS, and the installer offers disk encryption with geli so the system will require a passphrase before booting.
