decorate the references to root and lfs user

The references already correctly decorated are not changed because "if
it's not broken don't fix it".

[387a32af]13 <para>This chapter shows how to build the last missing bits of the temporary
[305c970]14 system: the tools needed by the build machinery of various packages. Now
15 that all circular dependencies have been resolved, a <quote>chroot</quote>
16 environment, completely isolated from the host operating system (except for
17 the running kernel), can be used for the build.</para>
19 <para>For proper operation of the isolated environment, some communication
20 with the running kernel must be established. This is done through the
21 so-called <emphasis>Virtual Kernel File Systems</emphasis>, which must be
22 mounted when entering the chroot environment. You may want to check
[387a32af]23 that they are mounted by issuing <command>findmnt</command>.</para>
25 <para>Until <xref linkend="ch-tools-chroot"/>, the commands must be
26 run as <systemitem class="username">root</systemitem>, with the
27 <envar>LFS</envar> variable set. After entering chroot, all commands
[2ad6d43]28 are run as &root;, fortunately without access to the OS of the computer
[387a32af]29 you built LFS on. Be careful anyway, as it is easy to destroy the whole
[ce335792]30 LFS system with badly formed commands.</para>
