We will create the partition itself, make a file system on it, 12 and mount it.</para> 13 14 </sect1> 12 <xi:include xmlns:xi="http://www.w3.org/2003/XInclude" href="introduction.xml"/> 15 13 16 14 17 <sect1 id="space-creatingpartition"> 18 <title>Creating a new partition</title> 19 <?dbhtml filename="creatingpartition.html" dir="chapter02"?> 20 21 <para>In order to build our new Linux system, we will need some space: 22 an empty disk partition. If you don't have a free partition, and no room 23 on any of your hard disks to make one, then you could build LFS on the 24 same partition as the one on which your current distribution is installed. 25 This procedure is not recommended for your first LFS install, but if you 26 are short on disk space, and you feel brave, take a look at the hint at 27 <ulink url="&hints-root;lfs_next_to_existing_systems.txt"/>.</para> 28 29 <para>For a minimal system you will need a partition of around 1.2 GB. 30 This is enough to store all the source tarballs and compile all the packages. 31 But if you intend to use the LFS system as your primary Linux system, you 32 will probably want to install additional software, and will need more space 33 than this, probably around 2 or 3 GB.</para> 34 35 <para>As we almost never have enough RAM in our box, it is a good idea to 36 use a small disk partition as swap space -- this space is used by the kernel 37 to store seldom-used data to make room in memory for more urgent stuff. 38 The swap partition for your LFS system can be the same one as for your host 39 system, so you won't have to create another if your host system already uses 40 a swap partition.</para> 41 42 <para>Start a disk partitioning program such as <command>cfdisk</command> 43 or <command>fdisk</command> with an argument naming the hard disk upon 44 which the new partition must be created -- for example 45 <filename>/dev/hda</filename> for the primary IDE disk. Create a Linux native 46 partition and a swap partition, if needed. Please refer to the man pages of 47 <command>cfdisk</command> or <command>fdisk</command> if you don't yet 48 know how to use the programs.</para> 49 50 <para>Remember the designation of your new partition -- something like 51 <filename>hda5</filename>. This book will refer to it as the LFS partition. 52 If you (now) also have a swap partition, remember its designation too. These 53 names will later be needed for the <filename>/etc/fstab</filename> file.</para> 54 55 </sect1> 15 <xi:include xmlns:xi="http://www.w3.org/2003/XInclude" href="creatingpartition.xml"/> 56 16 57 17 58 <sect1 id="space-creatingfilesystem"> 59 <title>Creating a file system on the new partition</title> 60 <?dbhtml filename="creatingfilesystem.html" dir="chapter02"?> 61 62 <para>Now that we have a blank partition, we can create a file system on it. 63 Most widely used in the Linux world is the second extended file system (ext2), 64 but with the high-capacity hard disks of today the so-called journaling 65 file systems are becoming increasingly popular. Here we will create an ext2 66 file system, but build instructions for other file systems can be found at 67 <ulink url="&blfs-root;view/stable/postlfs/filesystems.html"/>.</para> 68 69 <para>To create an ext2 file system on the LFS partition run the following:</para> 70 71 <screen><userinput>mke2fs /dev/xxx</userinput></screen> 72 73 <para>Replace <filename>xxx</filename> with the name of the LFS partition 74 (something like <filename>hda5</filename>).</para> 75 76 <para>If you created a (new) swap partition you need to initialize it as a 77 swap partition too (also known as formatting, like you did above with 78 <command>mke2fs</command>) by running:</para> 79 80 <screen><userinput>mkswap /dev/yyy</userinput></screen> 81 82 <para>Replace <filename>yyy</filename> with the name of the swap 83 partition.</para> 84 85 </sect1> 18 <xi:include xmlns:xi="http://www.w3.org/2003/XInclude" href="creatingfilesystem.xml"/> 86 19 87 20 88 <sect1 id="space-mounting"> 89 <title>Mounting the new partition</title> 90 <?dbhtml filename="mounting.html" dir="chapter02"?> 91 92 <para>Now that we've created a file system, we want to be able to access 93 the partition. For that, we need to mount it, and have to choose a mount 94 point. In this book we assume that the file system is mounted under 95 <filename>/mnt/lfs</filename>, but it doesn't matter what directory 96 you choose.</para> 97 98 <para>Choose a mount point and assign it to the LFS environment variable 99 by running:</para> 100 101 <screen><userinput>export LFS=/mnt/lfs</userinput></screen> 102 103 <para>Now create the mount point and mount the LFS file system by running:</para> 104 105 <screen><userinput>mkdir -p $LFS 106 mount /dev/xxx $LFS</userinput></screen> 107 108 <para>Replace <filename>xxx</filename> with the designation of the LFS 109 partition.</para> 110 111 <para>If you have decided to use multiple partitions for LFS (say one for 112 <filename>/</filename> and another for <filename>/usr</filename>), mount 113 them like this:</para> 114 115 <screen><userinput>mkdir -p $LFS 116 mount /dev/xxx $LFS 117 mkdir $LFS/usr 118 mount /dev/yyy $LFS/usr</userinput></screen> 119 120 <para>Of course, replace <filename>xxx</filename> and <filename>yyy</filename> 121 with the appropriate partition names.</para> 122 123 <para>You should also ensure that this new partition is not mounted with 124 permissions that are too restrictive (such as the nosuid, nodev or noatime 125 options). You can run the <command>mount</command> command without any 126 parameters to see with what options the LFS partition is mounted. If 127 you see nosuid, nodev or noatime, you will need to remount it.</para> 128 129 <para>Now that we've made ourselves a place to work in, we're ready to download 130 the packages.</para> 131 132 </sect1> 21 <xi:include xmlns:xi="http://www.w3.org/2003/XInclude" href="mounting.xml"/> 133 22 134 23
