Having worked in IT departments in schools for over 10 years, painful memories exist of the agony felt by staff and students alike over the time it took to perform operating system updates. This was made many, many times worse when people began using Chromebooks, where updates were carried out seamlessly in the background and all that was required to access the new version was a reboot of the device. This is one technology used by a more modern OS, where two partitions are used to store the current OS and the upgrade, and if anything fails, the boot can revert to the older version.
In this feature, we are going to introduce Fedora Silverblue (which uses the Gnome desktop environment), which is an operating system that uses very different techniques from those you are most likely familiar with to create an operating system. Other examples of this sort of operating system are Fedora Kinoite (using the KDE desktop environment), NixOS, which allows ultimate customisation by installing only what is configured, OpenSUSE’s MicroOS, Endless OS, Ubuntu Core and Chrome OS Flex.
