Abstract: The sysinstall tool has been the default system installer for FreeBSD for more than a decade now. While is it has proven itself to be reliable and resilient over the years, it doesn’t support many of the new features that FreeBSD offers, as well as being un-intuitive for desktop users, who expect an easy to use graphical front-end to perform their installation. To solve these two problems the “pc-sysinstall” backend was created and now is in usage for PC-BSD 8.0. This new installer backend provides much of the same functionality as sysinstall, while offering many new features such as support for ZFS, Encryption, mirroring, scriptable installs and the ability to work with different front-ends, such as a QT based GUI. The backend also supports installing regular FreeBSD, which allows server administrators to quickly perform an installation using the new disk features it offers.
