Where does the first process come from?

The last internal action of booting a Unix-based operating system results in the first single 'true' process, named init.

init has the process-ID of 1. It is the ancestor process of all subsequent processes.

In addition, because the operating system strives to maintain a hierarchical relationship amongst all processes, a process whose parent terminates is 'adopted' by the init process.
