<title>Creating the passwd and group files</title>
<?dbhtml filename="pwdgroup.html" dir="chapter06"?>
<para>In order for <emphasis>root</emphasis> to be able to login and for the
name "root" to be recognized, there need to be relevant entries in the
<filename>/etc/passwd</filename> and <filename>/etc/group</filename> files.</para>
<para>Create the <filename>/etc/passwd</filename> file by running the following
command:</para>
<para><screen><userinput>cat > /etc/passwd << "EOF"</userinput>
root:x:0:0:root:/root:/bin/bash
<userinput>EOF</userinput></screen></para>
<para>The actual password for <emphasis>root</emphasis> (the "x" here is just a
placeholder) will be set later.</para>
<para>Create the <filename>/etc/group</filename> file by running the following
command:</para>
<para><screen><userinput>cat > /etc/group << "EOF"</userinput>
root:x:0:
bin:x:1:
sys:x:2:
kmem:x:3:
tty:x:4:
tape:x:5:
daemon:x:6:
floppy:x:7:
disk:x:8:
lp:x:9:
dialout:x:10:
audio:x:11:
<userinput>EOF</userinput></screen></para>
<para>The created groups aren't part of any standard -- they are the groups
that the MAKEDEV script in the next section uses. Besides the group "root", the
LSB (<ulink url="http://www.linuxbase.org"/>) recommends only a group "bin",
with a GID of 1, be present. All other group names and GIDs can be chosen
freely by the user, as well-written packages don't depend on GID numbers but
use the group's name.</para>
<para>Lastly, we re-login to the chroot environment. User name and group name
resolution will start working immediately after the
<filename>/etc/passwd</filename> and <filename>/etc/group</filename> files are
created, because we installed a full glibc in Chapter 5. This will get rid of
the <quote>I have no name!</quote> prompt.</para>
<para><screen><userinput>exec /tools/bin/bash --login +h</userinput></screen></para>
