    53 <para>The created groups aren't part of any standard -- they are some of the
    54 groups that the Udev configuration we will be using in the next section
    55 uses. The LSB (<ulink url="http://www.linuxbase.org/">Linux Standard
    56 Base</ulink>) recommends only that, beside the group <quote>root</quote> with a
    57 GID of 0, a group <quote>bin</quote> with a GID of 1 be present. All other group
    58 names and GIDs can be chosen freely by the system administrator, since
    59 well-written packages don't depend on GID numbers but use the group's name.

    61 
    62 <para>To get rid of the <quote>I have no name!</quote> prompt, we will start a
    63 new shell.  Since we installed a full Glibc in
    64 <xref linkend="chapter-temporary-tools"/>, and have just created the
    65 <filename>/etc/passwd</filename> and <filename>/etc/group</filename> files,
    66 user name and group name resolution will now work.</para>

    70 <para>Note the use of the <parameter>+h</parameter> directive. This tells
    71 <command>bash</command> not to use its internal path hashing. Without this
    72 directive, <command>bash</command> would remember the paths to binaries it
    73 has executed. Since we want to use our newly compiled binaries as soon as
    74 they are installed, we turn off this function for the duration of this
    75 chapter.</para>

    77 <para>The <command>login</command>, <command>agetty</command> and
    78 <command>init</command> programs (and some others) use a number of log
    79 files to record information such as who was logged into the system and when.
    80 These programs, however, won't write to the log files if they don't already
    81 exist. Initialize the log files and give them their proper permissions:</para>
