.TH ROOT 3
.SH NAME
root \- the root file system
.SH SYNOPSIS
.nf
.B /
.B /boot
.B /dev
.B /env
.B /net
.B /net.alt
.B /proc
.B /root
.B /srv
.fi
.SH DESCRIPTION
The syntax
.L #/
is illegal, so this device can only be accessed directly by the kernel.
.PP
This device is set up by the kernel to be the root of
the name space.
The names in the one-level tree are mostly just place-holders,
to allow a place to
.IR bind (2)
to.
The exception is
.BR /boot ,
which contains
.B /boot/boot
and any files
.B /boot/boot
might need.
The kernel does an
.IR exec (2)
of
.B /boot/boot
when initializing.
