  <para>To remove the <quote>I have no name!</quote> prompt, start a
  new shell. Since a full Glibc was installed in <xref
  linkend="chapter-cross-tools"/> and the <filename>/etc/passwd</filename>
  and <filename>/etc/group</filename> files have been created, user name
  and group name resolution will now work.</para>

<screen role="nodump"><userinput>exec /tools/bin/bash --login +h</userinput></screen>

  <para>Note the use of the <parameter>+h</parameter> directive. This tells
  <command>bash</command> not to use its internal path hashing. Without this
  directive, <command>bash</command> would remember the paths to binaries it
  has executed. To ensure the use of the newly compiled binaries as soon as
  they are installed, the <parameter>+h</parameter> directive will be used
  for the duration of the next chapters.</para>
