      \item Used for essential system and
      maintenance utilities
      \item Programs in this directory generally
      used by privileged users
      \item Executable files in this directory used
      to boot and mount \filelink{/usr} (in addition
      to those in \filelink{/bin})
      \item Executable files in this directory used
      to perform system recovery operations (in
      addition to those in \filelink{/bin})

            recent distributions have abandoned the strategy of

            (as well as \filelink{/bin} and \filelink{/usr/bin})

\cprotect\note{

   This directory contains binaries essential for
   booting, restoring, recovering, and/or repairing in
   addition to those binaries in the \filelink{/bin}
   directory.  They also must be able to mount other
   filesystems on \filelink{/usr}, \filelink{/home} and
   other locations if needed, once the root filesystem
   is known to be in good health during boot.

   The following programs should be included in this
   directory (if their subsystems are installed):
   \begin{quote}
      \textbf{fdisk, fsck, getty, halt, ifconfig, init,
         mkfs, mkswap, reboot, route, swapon, swapoff,
         update}.
   \end{quote}
   \begin{cmd}
 $ ls -l /sbin
  \end{cmd}
   \begin{response}
rwxrwxrwx 1 root root 8 Apr 23  2020 /sbin -> usr/sbin

\cprotect\note {

   Recent distribution versions of \textbf{RHEL},
   \textbf{CentOS}, \textbf{Fedora}, and \textbf{Ubuntu}
   have symbolically linked \filelink{/sbin} and
   \filelink{/usr/sbin} so they are actually the same.

   The above screenshot is from \textbf{Ubuntu 18.04}; later
   versions no longer have a separate un-linked directory.
