The kernel un-compresses
-
The kernel claims a certain amount of memory for its working tables and buffers (kernel memory).
-
All the driver that are built into the kernel initialize by detecting their respective hardware
-
The kernel mounts the root file system The kernel mounts the root directory of the root file system to the kernels' idea of a system (superstructure) root directory.
-
The kernel executes /sbin/init
The kernel now waits for asynchronous events to occur; i.e. It is now ready to serve the system by servicing requests from processes and hardware.
Everything that happens subsequently on the system has to either be requested by a binary through a system call to the kernel, or an asynchronous event triggered by hardware
