|
<para>Throughout this book, the environment variable <envar>LFS</envar> will
|
|
be used several times. It is paramount that this variable is always defined.
|
|
It should be set to the mount point chosen for the LFS partition.
|
|
Check that the <envar>LFS</envar> variable is set up properly with:</para>
|
|
|
|
<screen><userinput>echo $LFS</userinput></screen>
|
|
|
|
<para>Make sure the output shows the path to the LFS partition's mount
|
|
point, which is <filename class="directory">/mnt/lfs</filename> if the
|
|
provided example was followed. If the output is incorrect, the
|
|
variable can be set with:</para>
|
|
|
|
<screen><userinput>export LFS=/mnt/lfs</userinput></screen>
|
|
|
|
<para>Having this variable set is beneficial in that commands such as
|
|
<command>mkdir $LFS/tools</command> can be typed literally. The shell
|
|
will automatically replace <quote>$LFS</quote> with
|
|
<quote>/mnt/lfs</quote> (or whatever the variable was set to) when it
|
|
processes the command line.</para>
|
|
|
|
<para>Do not forget to check that <envar>$LFS</envar> is set whenever
|
|
you leave and reenter the current working environment (as when doing a
|
|
<quote>su</quote> to <emphasis>root</emphasis> or another user).</para>
