[fa6e750] | 13 | <para>Currently, the <filename class="directory">/tools</filename> |
---|
| 14 | and <filename class="directory">/cross-tools</filename> directories |
---|
| 15 | are owned by the user <emphasis>lfs</emphasis>, a user that |
---|
| 16 | exists only on the host system. Although the <filename |
---|
| 17 | class="directory">/tools</filename> and <filename |
---|
| 18 | class="directory">/cross-tools</filename> directories can be deleted |
---|
| 19 | once the LFS system has been finished, they can be retained to build |
---|
| 20 | additional LFS systems. If the <filename class="directory">/tools</filename> |
---|
| 21 | and <filename class="directory">/cross-tools</filename> directories are |
---|
| 22 | kept as is, the files are owned by a user ID without a corresponding |
---|
| 23 | account. This is dangerous because a user account created later could |
---|
| 24 | get this same user ID and would own the <filename |
---|
| 25 | lass="directory">/tools</filename> directory and all the files therein, |
---|
| 26 | thus exposing these files to possible malicious manipulation.</para> |
