Setup devices and filesystems, mount root filesystem
Usage
#include <unistd.h>
[[deprecated]] int setup(void);

Overview
setup() is called once from within linux/init/main.c. It calls initialization functions for devices and filesystems configured into the kernel and then mounts the root filesystem.
No user process may call setup(). Any user process, even a process with superuser permission, will receive EPERM.
Return value
setup() always returns -1 for a user process.
Errors
- EPERM
-
Always, for a user process.
Versions
Removed in Linux 2.1.121.
The calling sequence varied: at some times setup() has had a single argument void *BIOS and at other times a single argument int magic.
Releases
19 releases since Debian 1.1 (Buzz); the text changed 15 times.
