11 <title>Creating a New Partition</title>

13 <para os="a">Like most other operating systems, CLFS is usually installed on
14 a dedicated partition. The recommended approach to building a CLFS
15 system is to use an available empty partition or, if you have enough
16 unpartitioned space, to create one. However, a CLFS system (in fact
17 even multiple CLFS systems) may also be installed on a partition already
18 occupied by another operating system and the different systems will
19 co-exist peacefully. The document <ulink
20 url="&hints-root;lfs_next_to_existing_systems.txt"/> explains how to
21 implement this, whereas this book discusses the method of using a fresh
22 partition for the installation.</para>
23
24 <para os="b">A minimal system requires a partition of around 1.3 gigabytes (GB).
25 This is enough to store all the source tarballs and compile the packages.
26 However, if the CLFS system is intended to be the primary Linux system,
27 additional software will probably be installed which will require
28 additional space (2-3 GB). The CLFS system itself will not take up this
29 much room. A large portion of this requirement is to provide sufficient
30 free temporary storage. Compiling packages can require a lot of disk space
31 which will be reclaimed after the package is installed.</para>
32
33 <para os="c">Because there is not always enough Random Access Memory (RAM)
34 available for compilation processes, it is a good idea to use a small disk
35 partition as swap space. This is used by the kernel to store seldom-used
36 data and leave more memory available for active processes. The swap
37 partition for an CLFS system can be the same as the one used by the host
38 system, in which case it is not necessary to create another one.</para>
39
40 <para os="d">Start a disk partitioning program such as <command>cfdisk</command>
41 or <command>fdisk</command> with a command line option naming the hard
42 disk on which the new partition will be created&mdash;for example
43 <filename class="devicefile">/dev/hda</filename> for the primary
44 Integrated Drive Electronics (IDE) disk. Create a Linux native partition
45 and a swap partition, if needed. Please refer to
46 <filename>cfdisk(8)</filename> or <filename>fdisk(8)</filename> if you
47 do not yet know how to use the programs.</para>
48
49 <para os="e">Remember the designation of the new partition (e.g.,
50 <filename class="devicefile">hda5</filename>). This book will refer to
51 this as the CLFS partition. Also remember the designation of the swap
52 partition. These names will be needed later for the
53 <filename>/etc/fstab</filename> file.</para>
