Gentoo Releases New LiveDVD (Gentoo 11.2)
This new Gentoo LiveDVD ships with the Linux 3.0 kernel, GCC 4.5.2, KDE 4.7.0, Xfce 4.8, GNOME 3.0, LibreOffice 3.3.3, Mozilla Firefox 5.0, Chomium 13.0, and a great deal of other updated packages.
The Gentoo 11.2 LiveDVD now has a writable file-system via AuFS, which means new packages can be emerged in a live mode too. Additionally, there's persistency support for the home directory.
