<title>Introduction</title>

|
|
<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>
