<p class="Pp">This section contains information related to system operation and
    maintenance.</p>
<p class="Pp">It describes commands used to create new file systems
    (<a class="Xr">newfs(8)</a>), verify the integrity of the file systems
    (<a class="Xr">fsck(8)</a>), control disk usage
    (<a class="Xr">edquota(8)</a>), maintain system backups
    (<a class="Xr">dump(8)</a>), and recover files when disks die an untimely
    death (<a class="Xr">restore(8)</a>). Network related services like
    <a class="Xr">inetd(8)</a> are also described.</p>
<p class="Pp">All commands set an exit status. Its value may be tested to see if
    the command completed normally. Unless otherwise noted (rare), the value 0
    signifies successful completion of the command, while a value &gt;0
    indicates an error. Some commands attempt to describe the nature of the
    failure by using error codes defined in <a class="Xr">sysexits(3)</a>, or
    set the status to arbitrary values &gt;0 (typically 1), but many such values
    are not described in the manual.</p>
<p class="Pp">A number of pages in this section describe general system
    management topics.</p>
<p class="Pp">For example, the <a class="Xr">boot(8)</a> manual page describes
    the system bootstrapping procedures, and the <a class="Xr">diskless(8)</a>
    manual page describes how to boot a system over a network. The
    <a class="Xr">crash(8)</a> manual page should be consulted to understand how
    to interpret system crash dumps.</p>
