Slackware-based Porteus live system update has Linux 3.4
The developers at the Porteus project have released version 1.2 of their portable Linux distribution. Porteus is a Slackware-based minimal live system that offers a choice of lightweight desktop environments including KDE 3 (Trinity), KDE 4, Xfce and LXDE. Using a "heavily modified version of the linux-live scripts", it has been optimised to run from portable media such as USB flash drives or CDs, and can be expanded using modules. Its developers say that, with its small footprint and modest system requirements, it is also ideal for running on netbooks.
Porteus 1.2 is a major update based on Slackware Linux 13.37 binary packages and the recent 3.4.4 Linux kernel, which also upgrades the included desktops and other components.
