Linux has become a reliable utility for creating operating systems for embedded systems. However, the learning curve for embedded development utilities can be quite challenging. Many people who use these complex tools have spent a lot of time understanding and mastering them, and Yocto is no different. With it, you can develop a custom minimal Linux distribution for your embedded system project.

In the future, we will be able to use such perfectly crafted virtual reality systems to be nigh indistinguishable from reality. Environments that aren't there, but you can see and feel them. Although we are not quite there yet for ourselves, we are there in the case of our computers.

The reboot command is used to reboot or restart the system in Linux.
