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

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