---|
12 | |
---|
13 | <para>Throughout this book, the environment variable <envar>CLFS</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 CLFS partition. |
---|
16 | For the purposes of this book, it is assumed that the file system |
---|
17 | will be mounted under <filename class="directory">/mnt/clfs</filename>, |
---|
18 | but the directory choice is up to you. Decide on a directory location and set |
---|
19 | the variable with the following command:</para> |
---|
20 | |
---|
21 | <screen><userinput>export CLFS=<replaceable>[/mnt/clfs]</replaceable></userinput></screen> |
---|
22 | |
---|
23 | <para>Having this variable set is beneficial in that commands such as |
---|
24 | <command>install -dv ${CLFS}/tools</command> can be typed literally. The shell |
---|
25 | will automatically replace <quote>${CLFS}</quote> with |
---|
26 | <quote>/mnt/clfs</quote> (or whatever the variable was set to) when it |
---|
27 | processes the command line.</para> |
---|
28 | |
---|
29 | <para>Do not forget to check that <envar>${CLFS}</envar> is set whenever |
---|
30 | you leave and reenter the current working environment (as when doing a |
---|
31 | <quote>su</quote> to <systemitem class="username">root</systemitem> or |
---|
32 | another user). Check that the <envar>CLFS</envar> variable is set up |
---|
33 | properly with:</para> |
---|
34 | |
---|
35 | <screen><userinput>echo ${CLFS}</userinput></screen> |
---|
36 | |
---|
37 | <para>Make sure the output shows the path to the CLFS partition's mount |
---|
38 | point, which is <filename class="directory">/mnt/clfs</filename> if the |
---|
39 | provided example was followed. If the output is incorrect, use the command |
---|
40 | given earlier on this page to set <envar>${CLFS}</envar> to the correct |
---|
41 | directory name.</para> |
