<title>Creating devices</title>

<para>Please note that unpacking the MAKEDEV-&makedev-version;.bz2 file
doesn't create a directory for you to <userinput>cd</userinput> into, as
the file only contains a single shell script.</para>

<para>Install the MAKEDEV script:</para>

<para><screen><userinput>bzcat MAKEDEV-&makedev-version;.bz2 &gt; /dev/MAKEDEV
chmod 754 /dev/MAKEDEV</userinput></screen></para>

<para>Run the script to create the device files:</para>

<para><screen><userinput>cd /dev
./MAKEDEV -v generic-nopty</userinput></screen></para>

<para>The meaning of the option:</para>

<itemizedlist>
<listitem><para><userinput>-v generic-nopty</userinput>: The
<userinput>-v</userinput> parameter tells the MAKEDEV script to run in verbose
mode. The <userinput>generic-nopty</userinput> parameter instructs MAKEDEV to
create a generic selection of commonly used device special files, except for the
ptyXX and ttyXX range of files. We don't need those files because we are going
to use Unix98 PTYs via the <emphasis>devpts</emphasis> file
system.</para></listitem>
</itemizedlist>

<para>If a device you need is missing, try running
<userinput>./MAKEDEV -v &lt;device&gt;</userinput>. Alternatively, you may
create devices via the <emphasis>mknod</emphasis> program. Please refer to
the man and info pages of <emphasis>mknod</emphasis> if you need more
information.</para>
