	There is no doubt that Liberté Linux meet its design goals. It allows a user to browse and communicate anonymously and securely in the most hostile of regions. In that sense, you can claim that liberté linux is a success. To meet this goal, the Liberte Linux distribution comes prepackaged with a wide variety of secure tools, such as: Midori (with tor enhancements), Claws Mail (with cable communication built in ~~-- discussed later in the report~~) etc.		There is no doubt that Liberté Linux meet its design goals.

	<!--Liberté Linux does not use a packaging format or utility to distribute binaries, because security is the number one concern. Consequently you must manually download, compile and install all applications. Therefore, there is no simple way to get a list of installed packages, nor is there an easy way to obtain a list of packages you can install. As such, this drastically complicates the addition and removal of applications and tools. Installation would solely depend on the application in question. Above and beyond this, the standard make/install tools are not available on the platform by default. Every time you want to install applications you must rebuild the USB image.		<!--Liberté Linux does not use a packaging format or utility to distribute binaries, because security is the number one concern.

	<tt>Init</tt> first starts by reading in the configuration from <tt>/etc/inittab</tt>. On Liberté linux, the first initialization step is to initialize the runlevel to runlevel 3. Then it proceeds to run the <tt>/sbin/rc sysinit </tt> command to mount local filesystems. There are two initialization scripts run here: [http://en.wikipedia.org/wiki/Device_file devfs], [http://en.wikipedia.org/wiki/Dmesg dmesg], [http://en.wikipedia.org/wiki/Udev udev]. At this point, only the udev processes are started.		<tt>Init</tt> first starts by reading in the configuration from <tt>/etc/inittab</tt>.
