Internal markup reworking to fix the extraneous whitespace problem in the "tidy generated" web site pages. Essentially replace all ocurrences of <para><screen> with <screen> (and of course the matching closing tags).

| [148bb04] | 5 | <para>Right now the <filename class="directory">/tools</filename> directory
|
|---|
| [b74e415] | 6 | is owned by the user <emphasis>lfs</emphasis>, a user that exists only on your
|
|---|
| 7 | host system. Although you will probably want to delete the
|
|---|
| [148bb04] | 8 | <filename class="directory">/tools</filename> directory once you have
|
|---|
| [b74e415] | 9 | finished your LFS system, you may want to keep it around, for example to
|
|---|
| 10 | build more LFS systems. But if you keep the
|
|---|
| [148bb04] | 11 | <filename class="directory">/tools</filename> directory as it is, you end up
|
|---|
| [b74e415] | 12 | with files owned by a user ID without a corresponding account. This is
|
|---|
| 13 | dangerous because a user account created later on could get this same user ID
|
|---|
| [148bb04] | 14 | and would suddenly own the <filename class="directory">/tools</filename>
|
|---|
| [b74e415] | 15 | directory and all the files therein, thus exposing these files to possible
|
|---|
| 16 | malicious manipulation.</para>
|

| [062461b] | 17 |
|
|---|
| [b74e415] | 18 | <para>To avoid this issue, you could add the <emphasis>lfs</emphasis> user to
|
|---|
| 19 | your new LFS system later on when creating the <filename>/etc/passwd</filename>
|
|---|
| 20 | file, taking care to assign it the same user and group IDs as on your host
|
|---|
| 21 | system. Alternatively, you can (and the book assumes you do) assign the
|
|---|
| [148bb04] | 22 | contents of the <filename class="directory">/tools</filename> directory to
|
|---|
| [b74e415] | 23 | user <emphasis>root</emphasis> by running the following command:</para>
|
|---|
| [062461b] | 24 |
|
|---|
| [21ba4e3] | 25 | <screen><userinput>chown -R 0:0 /tools</userinput></screen>
|
|---|
| [44c2fd8] | 26 |
|
|---|
| [d066924] | 27 | <para>The command uses "0:0" instead of "root:root", because chown is unable
|
|---|
| [c94dd38] | 28 | to resolve the name "root" until the password file has been created.</para>
