<para>This chapter shows how to build the last missing bits of the temporary

system: the tools needed by the build machinery of various packages. Now
that all circular dependencies have been resolved and the temporary system
is already bootable, we can boot it on the target machine and it would be
completely isolated from the host operating system. Then we can continue
to build on the target machine.</para>
<para>For proper operation of the temporary system, some communication
with the running kernel must be established. This is done through the
so-called <emphasis>Virtual Kernel File Systems</emphasis>, which must be
mounted as soon as possible after boot. You may want to check
that they are mounted by issuing <command>mount</command>.</para>
<para>All commands in this and following chapters are run as root on the
target system, fortunately without access to the host system.
Be careful anyway, as if the storage devices of your target system already
contain some important data, it's possible to destroy them with badly
formed commands.</para>
