<title>Creating a New Partition</title>
<para>Like most other operating systems, LFS is usually installed on a
dedicated partition. The recommended approach to building an LFS system
is to use an available empty partition or, if you have enough unpartitioned
space, to create one. However, an LFS system (in fact even multiple LFS
systems) may also be installed on a partition already occupied by another
operating system and the different systems will co-exist peacefully. The
document <ulink url="&hints-root;lfs_next_to_existing_systems.txt"/>
explains how to implement this, whereas this book discusses the method of
using a fresh partition for the installation.</para>
<para>A minimal system requires a partition of around 1.3 gigabytes (GB).
This is enough to store all the source tarballs and compile the packages.
However, if the LFS system is intended to be the primary Linux system,
additional software will probably be installed which will require additional
space (2-3 GB). The LFS system itself will not take up this much room.
A large portion of this requirement is to provide sufficient free temporary
storage. Compiling packages can require a lot of disk space which will be
reclaimed after the package is installed.</para>
<para>Because there is not always enough Random Access Memory (RAM) available
for compilation processes, it is a good idea to use a small disk partition as
<systemitem class="filesystem">swap</systemitem> space. This is used by the
kernel to store seldom-used data and leave more memory available for active
processes. The <systemitem class="filesystem">swap</systemitem> partition for
an LFS system can be the same as the one used by the host system, in which
case it is not necessary to create another one.</para>
<para>Start a disk partitioning program such as <command>cfdisk</command>
or <command>fdisk</command> with a command line option naming the hard
disk on which the new partition will be created—for example
<filename class="devicefile">/dev/hda</filename> for the primary Integrated
Drive Electronics (IDE) disk. Create a Linux native partition and a
<systemitem class="filesystem">swap</systemitem> partition, if needed. Please
refer to <filename>cfdisk(8)</filename> or <filename>fdisk(8)</filename> if
you do not yet know how to use the programs.</para>
<para>Remember the designation of the new partition (e.g., <filename
class="devicefile">hda5</filename>). This book will refer to this as
the LFS partition. Also remember the designation of the <systemitem
class="filesystem">swap</systemitem> partition. These names will be
needed later for the <filename>/etc/fstab</filename> file.</para>
