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

|

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