    <title>Mounting Additional Kernel Filesystems</title>

    <para>Mount the proper virtual (kernel) file systems on the
    newly-created directories:</para>

<screen><userinput>mount -vt devpts -o gid=&gid-tty;,mode=620 none /dev/pts
mount -vt tmpfs none /dev/shm</userinput></screen>

    <para>The <command>mount</command> commands executed above may result
    in the following warning message:</para>

<screen><computeroutput>can't open /etc/fstab: No such file or directory.</computeroutput></screen>

    <para>This file&mdash;<filename>/etc/fstab</filename>&mdash;has not
    been created yet (unless using the boot method), but is also not required
    for the file systems to be properly mounted. The warning can be safely
    ignored.</para>
