|
<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. Also, to support one of the coreutils
|
|
tests, we will also create the user and group nobody, which is almost
|
|
universally present on Linux computers.</para>
|
|
|
|
<para>Create the <filename>/etc/passwd</filename> file by running the
|
|
following command:</para>

<para>The actual password for <emphasis>root</emphasis> (the "x" here is

just a placeholder) will be set later.</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>
