Boot

What is this?

Boot is a component of the shell that handles a sequence of events from the moment a computer is powered on until the operating system is fully loaded.

Some features of Boot include:

Progress bar showing status of boot process, hiding all actions from user by default;
Power-on self-test (POST), which is run when the hardware receives power, verifies essential hardware components are installed and functioning;
Firmware initialisation and device discovery, which scans for bootable devices and looks for bootloaders;
Bootloader execution, which is loaded by firmware into memory, and handles hardware abstraction, kernel loading, and parameter passing;
Kernel initialisation, where the kernel takes control and handles hardware detection, driver loading, file system mounting, and process creation;
System initialisation, which reads its configuration to determine the target state of the system, starting essential system services; and
User space handoff, which loads the login prompt.
