| 10 | <para>Like most other operating systems, LFS is usually installed on
|
|---|
| 11 | a dedicated partition. The recommended approach to building an LFS
|
|---|
| 12 | system is to use an available empty partition or, if you have enough
|
|---|
| 13 | unpartitioned space, to create one. However, an LFS system (in
|
|---|
| 14 | fact even multiple LFS systems) may also be installed on a partition
|
|---|
| 15 | already occupied by another operating system and the different systems
|
|---|
| 16 | will co-exist peacefully. The document
|
|---|
| 17 | <ulink url="&hints-root;lfs_next_to_existing_systems.txt"/> explains
|
|---|
| 18 | how to implement this, whereas this book discusses the method of
|
|---|
| 19 | using a fresh partition for the installation.</para>
|

|

| 21 | <para>A minimal system requires a partition of around 1.3 gigabytes
|
|---|
| 22 | (GB). This is enough to store all the source tarballs and compile
|
|---|
| 23 | the packages. However, if the LFS system is intended to be the primary
|
|---|
| 24 | Linux system, additional software will probably be installed which
|
|---|
| 25 | will require additional space (2-3 GB). The LFS system itself will
|
|---|
| 26 | not take up this much room. A large portion of this requirement
|
|---|
| 27 | is to provide sufficient free temporary storage. Compiling
|
|---|
| 28 | packages can require a lot of disk space which will be reclaimed after
|
|---|
| 29 | the package is installed.</para>
|
|---|
| 30 |
|
|---|
| 31 | <para>Because there is not always enough Random Access Memory (RAM)
|
|---|
| 32 | available for compilation processes, it is a good idea to use a small
|
|---|
| 33 | disk partition as swap space. This is used by the kernel to
|
|---|
| 34 | store seldom-used data and leave more memory available for active processes.
|
|---|
| 35 | The swap partition for an LFS system can be the same as the one used
|
|---|
| 36 | by the host system, in which case it is not necessary to create another
|
|---|
| 37 | one.</para>
|
|---|
| 38 |
|
|---|
| 39 | <para>Start a disk partitioning program such as
|
|---|
| 40 | <command>cfdisk</command> or <command>fdisk</command> with a command
|
|---|
| 41 | line option naming the hard disk on which the new partition will be
|
|---|
| 42 | created—for example <filename class="devicefile">/dev/hda</filename> for
|
|---|
| 43 | the primary Integrated Drive Electronics (IDE) disk. Create a Linux native
|
|---|
| 44 | partition and a swap partition, if needed. Please refer to the man
|
|---|
| 45 | pages of <command>cfdisk</command> or <command>fdisk</command> if you
|
|---|
| 46 | do not yet know how to use the programs.</para>
|
|---|
| 47 |
|
|---|
| 48 | <para>Remember the designation of the new partition (e.g.,
|
|---|
| 49 | <filename class="devicefile">hda5</filename>). This book will refer to this as the LFS
|
|---|
| 50 | partition. Also remember the designation of the swap partition. These
|
|---|
| 51 | names will be needed later for the <filename>/etc/fstab</filename>
|
|---|
| 52 | file.</para>
