Filesystem Hierarchy Standard

3.2 /boot : Static files of the boot loader

This directory contains everything required for the boot process except configuration files and the map installer. Thus /boot stores data that is used before the kernel begins executing user-mode programs. This may include saved master boot sectors, sector map files, and other data that is not directly edited by hand. Programs necessary to arrange for the boot loader to be able to boot a file should be placed in /sbin. Configuration files for boot loaders should be placed in /etc.

The operating system kernel should be located in either / or /boot.

Note: On some i386 machines, it may be necessary for /boot to be located on a separate partition located completely below cylinder 1024 of the boot device due to hardware constraints.

Certain MIPS systems require a /boot partition that is a mounted MS-DOS filesystem or whatever other filesystem type is accessible for the firmware. This may result in restrictions with respect to usable filenames for /boot (only for affected systems).
