11 | <title>Creating a New Partition</title> |
---|
12 | |
---|
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> |
