By shedding the constraints of the FHS [0] it's able to completely rethink how the different components of an operating system interact with each other. It's like going from assembly to a language with functions. Dependencies can be analysed, can be encapsulated. Your OS becomes the output of a build file, not some porcelain edifice of /etc/ files. 'Rollback' is nonsensical, you just run the old build. I boot to a tmpfs root so all my changes are ephemeral unless I deliberately save them, it's a fresh install on every boot. 0: https://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standard https://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standard
