<para>Linux discriminates between 'normal' executables and those used for system maintenance or administrative tasks. The latter reside either here or - the less important ones - in /usr/sbin. Locally installed system administration programs should be placed into /usr/local/sbin. Programs executed after /usr is known to be mounted (when there are no problems) are generally placed into /usr/sbin. This directory contains all the binaries that are essential to the working of the system. These include system administration as well as maintenance and hardware configuration programs. You may find lilo, fdisk, init, ifconfig, etc here. These are the essential programs that are required by all the users. Another directory that contains system binaries is /usr/sbin. This directory contains other binaries of use to the system administrator. This is where you will find the network daemons for your system along with other binaries that only the system administrator has access to, but which are not required for system maintenance and repair. For obvious security reasons, these directories are never part of normal user's $PATHs, only of roots (PATH is an environment variable that controls the sequence of locations that the system will attempt to look in for commands).</para>
