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