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.
