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

| 13 | <para os="a">Like most other operating systems, LFS is usually installed on
|
|---|
| 14 | a dedicated partition. The recommended approach to building an LFS
|
|---|
| 15 | system is to use an available empty partition or, if you have enough
|
|---|
| 16 | unpartitioned space, to create one. However, an LFS system (in fact
|
|---|
| 17 | even multiple LFS 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 LFS 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 LFS 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 LFS 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—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 LFS 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>
