Many embedded systems do not have a disk or a file system.Linux does not need either one to run.As mentioned before,the application tasks can be compiled along with the kernel and loaded as one image at boot time.This is sufficient for simple systems.In fact,if you look at many commercial embedded systems,you'll see that they offer file systems as options.Most are either a proprietary file system or an MS-DOS-compatible file system.Linux offers an MS-DOS-compatible file system,as well as a number of other choices.The other choices are usually recommended,because they are more robust and fault-tolerant.Linux also has check and repair utilities,generally missing in offerings from commercial vendors.This is especially important for flash systems which are updated over a network.If the system loses power in the middle of an upgrade,it can become unusable.A repair utility can usually fix such problems.
