[6a3b6af] | 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>
|
---|
[81fd230] | 17 |
|
---|
[447c9fa] | 18 | <screen role="nodump"><userinput>echo $LFS</userinput></screen>
|
---|
[81fd230] | 19 |
|
---|
[6a3b6af] | 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>
|
---|
[81fd230] | 24 |
|
---|
[447c9fa] | 25 | <screen role="nodump"><userinput>export LFS=/mnt/lfs</userinput></screen>
|
---|
[81fd230] | 26 |
|
---|
[6a3b6af] | 27 | <para>Having this variable set is beneficial in that commands such as
|
---|
| 28 | <command>mkdir $LFS/tools</command> can be typed literally. The shell
|
---|
| 29 | will automatically replace <quote>$LFS</quote> with
|
---|
| 30 | <quote>/mnt/lfs</quote> (or whatever the variable was set to) when it
|
---|
| 31 | processes the command line.</para>
|
---|
[81fd230] | 32 |
|
---|
[6a3b6af] | 33 | <para>Do not forget to check that <envar>$LFS</envar> is set whenever
|
---|
| 34 | you leave and reenter the current working environment (as when doing a
|
---|
| 35 | <command>su</command> to <systemitem class="username">root</systemitem>
|
---|
| 36 | or another user).</para>
