MontaVista's Mobilinux 5.0 brings a host of new features to the mobile-phone space. At the top of the list is Micro-SELinux, MontaVista's subset of the NSA-sponsored SELinux (Security Enhanced Linux). Pruning SELinux allows mandatory, policy-based access control to be implemented on low-end embedded platforms. The basic Mobilinux weighs in under 2 Mbytes, though typical systems are on the order of 16 Mbytes. Mobilinux boots quickly (under 5 s), enabling a cell call to be placed in under 10 s. Advanced powermanagement support can extend battery life up to 80%. Other benefits include low-level kernel debugging over a USB link as well as support for a host of mobile peripherals, including Bluetooth, SDIO, and USB. Mobilinux is bundled with MontaVista's open-source development tools and the Eclipse-based DevRocket integrated development environment (IDE). Mobilinux is sold using an annual subscription service.
