39 <para>This section is not strictly required for LFS if not using
40 systemd. On the other hand, ninja associated to meson makes
41 a powerful build system combination,

52 <para>When run, ninja normally runs a maximum number of processes
53 in parallel. By default this is the number of cores on the system
54 plus two. In some cases this can overheat a CPU or run a system out
55 of memory. If run from the command line, passing a -jN parameter
56 will limit the number of parallel processes, but some packages
57 embed the execution of ninja and do not pass a -j parameter.</para>
58
59 <para>Using the <emphasis>optional</emphasis> procedure below allows a user to
60 limit the number of parallel processes via an environment variable,
