-      <para>When laying out file systems, remember that hard drives
-	transfer data faster from the outer tracks to the inner.
-	Thus, smaller and heavier-accessed file systems should be
-	closer to the outside of the drive, while larger partitions
-	like <filename>/usr</filename> should be placed toward the
-	inner parts of the disk.  It is a good idea to create
-	partitions in an order similar to: <filename>/</filename>,
-	swap, <filename>/var</filename>, and
-	<filename>/usr</filename>.</para>
-
-      <para>The size of the <filename>/var</filename> partition
-	reflects the intended machine's usage.  This partition is
-	used to hold mailboxes, log files, and printer spools.
-	Mailboxes and log files can grow to unexpected sizes
-	depending on the number of users and how long log files are
-	kept.  On average, most users rarely need more than about a
-	gigabyte of free disk space in
-	<filename>/var</filename>.</para>
-
-      <note>
-	<para>Sometimes, a lot of disk space is required in
-	  <filename>/var/tmp</filename>.  When new software is
-	  installed, the packaging tools extract a temporary copy of
-	  the packages under <filename>/var/tmp</filename>.  Large
-	  software packages, like <application>Firefox</application>,
-	  <application>OpenOffice</application> or
-	  <application>LibreOffice</application> may be tricky to
-	  install if there is not enough disk space under
-	  <filename>/var/tmp</filename>.</para>
-      </note>
-
-      <para>The <filename>/usr</filename> partition holds many of the
-	files which support the system, including the &os; Ports
-	Collection and system source code.  At least 2 gigabytes is
-	recommended for this partition.</para>
-
-      <para>When selecting partition sizes, keep the space
-	requirements in mind.  Running out of space in one partition
-	while barely using another can be a hassle.</para>

-      <para>As a rule of thumb, the swap partition should be about
-	double the size of physical memory (<acronym>RAM</acronym>).
-	Systems with minimal <acronym>RAM</acronym> may perform
-	better with more swap.  Configuring too little swap can lead
-	to inefficiencies in the <acronym>VM</acronym> page scanning
-	code and might create issues later if more memory is
-	added.</para>
-
-      <para>On larger systems with multiple <acronym>SCSI</acronym>
-	disks or multiple <acronym>IDE</acronym> disks operating on
-	different controllers, it is recommended that swap be
-	configured on each drive, up to four drives.  The swap
-	partitions should be approximately the same size.  The
-	kernel can handle arbitrary sizes but internal data structures
-	scale to 4 times the largest swap partition.  Keeping the swap
-	partitions near the same size will allow the kernel to
-	optimally stripe swap space across disks.  Large swap sizes
-	are fine, even if swap is not used much.  It might be easier
-	to recover from a runaway program before being forced to
-	reboot.</para>
-
-      <para>By properly partitioning a system, fragmentation
-	introduced in the smaller write heavy partitions will not
-	bleed over into the mostly read partitions.  Keeping the
-	write loaded partitions closer to the disk's edge will
-	increase <acronym> I/O</acronym> performance in the
-	partitions where it occurs the most.  While
-	<acronym>I/O</acronym> performance in the larger partitions
-	may be needed, shifting them more toward the edge of the disk
-	will not lead to a significant performance improvement over
-	moving <filename>/var</filename> to the edge.</para>

-	<para>Proper sector alignment provides the best performance,
