NAME

setup - setup devices and file systems, mount root file system  

SYNOPSIS

#include <unistd.h>

_syscall0(int, setup);

int setup(void);  

DESCRIPTION

setup is called once from within linux/init/main.c. It calls initialization functions for devices and file systems configured into the kernel and then mounts the root file system.

No user process may call setup. Any user process, even a process with super-user permission, will receive EPERM.  

RETURN VALUE

setup always returns -1 for a user process.
