Why FreeBSD Is My Favorite *nix OS
FreeBSD provides a very easy installation process; it uses Sysinstall as an automated installation package to do it for you. All you have to do is answer some questions to create users and tell it which software to install and you are on your way to being up and running in a matter of minutes. The full installation takes longer that a few minutes to complete, but using Sysinstall to set the installation parameters is very quick. This installer takes care of everything needed to have FreeBSD installed and functioning correctly on your system, including user creation, software/application installations, network and peripheral setup, and much more.
FreeBSD is one of the most secure operating systems available. There are a number of security features built into the system that deal with user and file system security. There are also a number of applications compatible with FreeBSD that offer added security beyond the default features. Besides the basic user permissions modified through CHMOD, FreeBSD offers the ability to use ACL and MAC.
