configured into the kernel and then mounts the root file system.

R setup ().
Any user process, even a process with superuser permission,
will receive
R EPERM .
RETURN VALUE
R setup ()
always returns -1 for a user process.
ERRORS
EPERM
Always, for a user process.
CONFORMING TO
This function is Linux specific, and should not be used in programs
intended to be portable, or indeed in any programs at all.
Since Linux 2.1.121, no such function exists anymore.
The calling sequence varied: it has had a single parameter
void *BIOS
and at other times a single parameter
R int magic .
