5<para>The <filename>/etc/skel</filename> directory is quite simple
6to setup and use. It provides a way to make sure that all new users on
7your LFS system begin with the same settings. The
8<filename>/etc/skel</filename> directory is used by the
9<filename>/usr/sbin/useradd</filename> program.</para>
10
11<para>For more information see <filename>man useradd</filename>.</para>
12
13<para>To get started create a <filename>/etc/skel</filename> directory.
14Creating the directory as root is the best way to go. Next copy any
15files into <filename>/etc/skel</filename> that you want every new user
16to have placed in their home drive. Examples include
17<filename>.bash_profile</filename>, <filename>.bashrc</filename>,
18<filename>.bash_logout</filename>, <filename>dircolors</filename>,
19<filename>.inputrc</filename>, and <filename>.vimrc</filename>.</para>
20
21<para>When creating a new user with
22<filename>/usr/sbin/useradd</filename> use the <userinput>-m</userinput>
23parameter. For example:</para>
24
25<para><screen>[prompt]#<userinput>useradd -m -s/bin/bash
26jwrober</userinput></screen></para>
27
28<para>The <filename>/usr/sbin/useradd</filename> program uses a
29collection of default values. It will read them from the
30<filename>/etc/default/useradd</filename> file if it exists. If the
31file does not exist, then it uses some internal defaults. They can be
32found by running <userinput>/usr/sbin/useradd -D</userinput>.</para>
33
34<para>To change these values to something new, create a base
35<filename>/etc/default/useradd</filename> file with the same values as
36the output of <userinput>/usr/sbin/useradd -D</userinput>. Here is a
37sample.</para>
38
39<para><screen># Begin /etc/default/useradd
40
41GROUP=100
42HOME=/home
43INACTIVE=-1
44EXPIRE=
45SHELL=
46SKEL=/etc/skel
47
48# End /etc/default/useradd</screen></para>
49
50<para>The only thing missing from the file is a default shell. Add that
51by running:</para>
52
53<para><screen><userinput>/usr/sbin/useradd -D
54-s/bin/bash</userinput></screen></para>
55
56<para>This will set the <userinput>SHELL=</userinput> line to
57<userinput>SHELL=/bin/bash</userinput>. This makes it even easier to
58add new users to your LFS system. The
59<filename>/usr/sbin/useradd</filename> has many parameters that can be
60set in the <filename>/etc/default/useradd</filename> file. See the man
61page for more details.</para>
