If it's not the case, you should go to <a class="xref" href="squashfs.html" title="2.1.�Squashfs 4.2">squashfs 4.2</a>
You should also have configured your kernel properly, as described in <a class="xref" href="essential.html" title="3.1.�Reconfiguring the Kernel">Section�3.1, “Reconfiguring the Kernel”</a>
</p><p>Now it's time to assemble our live system.</p><p>First let's define the name of our system, this name will be given to our media: cd/dvd/usbkey/usbdrive.</p><p>The cd/dvd choice will be further mentioned as the ISO live system, the usbkey, usbdrive or usbstick will be mentioned as the usb live system</p><p>export the name of our system:</p><pre class="userinput"><kbd class="command">export LFSLIVE=lfslive</kbd></pre><p>create and export the mount point:</p><pre class="userinput"><kbd class="command">export LFSMOUNT=/mnt/LFS
mkdir -pv $LFSMOUNT</kbd></pre><p>If you plan to create an ISO live system, create some space to store the complete system plus some extra space. App. 1,5 times the size of the system will do,
after you reserved some space, create a link to the folder:</p><pre class="userinput"><kbd class="command">mount --bind <path to LFSspace> $LFSMOUNT</kbd></pre><p>Or if you use a dedicated partition mount it:</p><pre class="userinput"><kbd class="command">mount /dev/<device> $LFSMOUNT</kbd></pre><p>you can now continue with <a class="xref" href="building_iso.html" title="8.1.�Building the ISO live system">Section�8.1, “Building the ISO live system”</a></p><p></p><p>For use of the usb live system, it's time to create some free space on it and create partitions, just like we do in the LFS book;
Make an ext2 or ext3 file system on it and a small swap partition.</p><p>First, open the key with your favorite partitioning program, eg. cfdisk or fdisk or some other, and remove any partition already existing on it.
Then, create one primary partition on the usb stick.</p><p>You will then have to create ext2/ext3 filesystem on the partition you created, using:</p><pre class="userinput"><kbd class="command">mke2fs -j -L $LFSLIVE /dev/<sd?1></kbd></pre><p>Where sd?1 is the flash drive partition for the livekey</p><p>And mount it:</p><pre class="userinput"><kbd class="command">mount /dev/<device> $LFSMOUNT</kbd></pre><p>Now that the filesystem has been set up on the usb-media, go to <a class="xref" href="building.html" title="6.1.�Building the USB live system">Section�6.1, “Building the USB live system”</a></p></div><div class="navfooter"><ul><li class="prev"><a accesskey="p" href="ch05.html" title="Preparing install">Prev</a><p>Preparing install</p></li><li class="next"><a accesskey="n" href="pt05.html" title="the USB live system">Next</a><p>the USB live system</p></li><li class="up"><a accesskey="u" href="ch05.html" title="Chapter�5.�Preparing install">Up</a></li><li class="home"><a accesskey="h" href="index.html" title="LFS live howto - Version 0.3">Home</a></li></ul></div></body></html>
