Unobtrusiveness Liberté promptly installs as a regular directory on a USB/SD key, taking ≈200 MiB of disk space, and not interfering with other files present on the media. Everything is preconfigured — the only user input required during boot is the encrypted volume password. System requirements are just as lightweight: ≈192 MiB of RAM are entirely sufficient for unrestricted desktop use.
Security Liberté Linux is shipped with the Hardened Gentoo kernel, which includes all grsecurity/PaX security enhancements — radically improving system's resistance to software exploits. Measures like service privileges separation provide additional protection.
Persistence All persistent changes are kept in a secure LUKS/OTFE volume, easily accessible from any operating system. This includes application settings that are archived upon shutdown, as well as any documents explicitly stored in the encrypted volume. The OTFE volume is just a file on the boot media that can be copied, backed up, or transparently resized from inside Liberté.
Communication You can securely, reliably and covertly communicate with other Liberté Linux users via the familiar e-mail interface, using serverless cables communication — a CMS standard-based stateless messaging protocol.
Anonymity All networking activities like browsing and chatting are automatically Torified, with I2P locations transparently available as well. After the system receives a network address, the only external traffic it emits is encrypted communication on HTTP(S) ports (used by Tor). No other traffic is sent — not even DNS requests. I2P traffic is routed through Tor, too: you will be able to use I2P even behind the most restrictive firewalls. In addition, a special Unsafe Browser is available for the express purpose of registration in open Wi-Fi hotspots, if necessary.
Invariance Besides the encrypted volume on the boot media, Liberté leaves no traces in the system without explicit user consent (such as manually creating files on external automounted media). Moreover, all volatile memory is thoroughly erased upon shutdown in order to prevent cold boot attacks — whether an orderly shutdown, or an immediate one due to abrupt removal of the boot media.
Privacy Many other privacy-enhancing features, such as wireless MAC addresses randomization and uniform HTTP headers, are automatically employed in order to prevent pinpointing your activities.
Desktop More mundane yet useful applications, like document and image processing, are included as well. Do not be put off by its small image size — Liberté Linux is a fully capable distribution with HTML5 video support in the browser, file managers and chat plugins, audio players, a multitude of multilingual fonts, full application interface and keyboard localization, and much more.
Integrity The transparent and readily reproducible deployment image build process employs rigorous verification of the complete chain of trust of all downloaded archives, packages and signature keys. All software in the image, without exception, is built from source — there is no reliance on externally compiled binary executables. With reasonable competence, you can quickly master a customized image yourself.
Even though the precise terms of ACTA remain undecided, the negotiants' preliminary documents reveal many troubling aspects of the proposed agreement" such as removing "legal safeguards that protect Internet Service Providers from liability for the actions of their subscribers" in effect giving ISPs no option but to comply with privacy invasions.
