---|
| 12 | |
---|
| 13 | <para>Throughout this book, the environment variable <envar>LFS</envar> will |
---|
| 14 | be used several times. It is paramount that this variable is always defined. |
---|
| 15 | It should be set to the mount point chosen for the LFS partition. |
---|
| 16 | Check that the <envar>LFS</envar> variable is set up properly with:</para> |
---|
| 17 | |
---|
| 18 | <screen><userinput>echo $LFS</userinput></screen> |
---|
| 19 | |
---|
| 20 | <para>Make sure the output shows the path to the LFS partition's mount |
---|
| 21 | point, which is <filename class="directory">/mnt/lfs</filename> if the |
---|
| 22 | provided example was followed. If the output is incorrect, the |
---|
| 23 | variable can be set with:</para> |
---|
| 24 | |
---|
| 25 | <screen><userinput>export LFS=/mnt/lfs</userinput></screen> |
---|
| 26 | |
---|
| 27 | <para>Having this variable set is beneficial in that commands such as |
---|
| 28 | <command>install -d $LFS/tools</command> can be typed literally. The shell |
---|
| 29 | will automatically replace <quote>$LFS</quote> with |
---|
| 30 | <quote>/mnt/lfs</quote> (or whatever the variable was set to) when it |
---|
| 31 | processes the command line.</para> |
---|
| 32 | |
---|
| 33 | <para>If you haven't created the <filename class="directory">/mnt/lfs</filename> |
---|
| 34 | directory, do so at this time by issuing the following commands:</para> |
---|
| 35 | |
---|
| 36 | <screen><userinput>install -d $LFS</userinput></screen> |
---|
| 37 | |
---|
| 38 | <para>Do not forget to check that <envar>$LFS</envar> is set whenever |
---|
| 39 | you leave and reenter the current working environment (as when doing a |
---|
| 40 | <quote>su</quote> to <systemitem class="username">root</systemitem> or |
---|
| 41 | another user).</para> |
