Unix System Calls Question:
The very first process created by the Kernel in UNIX is?
Answer:
When the kernel begins to run, it starts by setting up a
number of internal lists, or tables.After initializing its
tables, the kernel creates three dummy processes; sched,
vhand and bdflush (with process IDs 0, 2 and 3
respectively). Finally the kernel creates a third process
init which pid 1. init starts up as a dummy process, then
achieves independence and runs as the first true process on
the system.
