Line 1:		Line 1:
			Embedded systems in general and Armadeus boards in particular have reached a CPU power level that allow them to now run Dekstop equivalent Linux distributions.
			The only remaining problem was the non volatile storage medium. Indeed most embedded systems come with less than 256MBytes of FLASH and so are unable to install a "normal" Linux distribution like debian for example.
			Problem has recently been resolved by the Emdebian project which provide size optimized debian packages. Resulting rootfs is still far from compactness of Buildroot's generated one but start to be usable on the APF configurations.
