Read only root filesystem

Read only root filesystem

The idea of operating system's root filesystem being used in read-only mode originates from Linux and creation of Live CD environments.

There are also some advantages of using a read-only-root system as a desktop, mainly increased security and user privacy.

Creation of read-only root Linux systems

Two methods are commonly used:
* mounting unionfs at root,
* mounting tmpfs at /var, /tmp and other places when write access is desired.
