+@subsection Common Build Options
+
+A number of options that control the build process are common to
+@command{guix build} and other commands that can spawn builds, such as
+@command{guix package} or @command{guix archive}. These are the
+following:
+
+@table @code
+
+@item --load-path=@var{directory}
+@itemx -L @var{directory}
+Add @var{directory} to the front of the package module search path
+(@pxref{Package Modules}).
+
+This allows users to define their own packages and make them visible to
+the command-line tools.
+
+@item --keep-failed
+@itemx -K
+Keep the build tree of failed builds. Thus, if a build fail, its build
+tree is kept under @file{/tmp}, in a directory whose name is shown at
+the end of the build log. This is useful when debugging build issues.
+
+@item --keep-going
+@itemx -k
+Keep going when some of the derivations fail to build; return only once
+all the builds have either completed or failed.
+
+The default behavior is to stop as soon as one of the specified
+derivations has failed.
+
+@item --dry-run
+@itemx -n
+Do not build the derivations.
+
+@item --fallback
+When substituting a pre-built binary fails, fall back to building
+packages locally.
+
+@item --substitute-urls=@var{urls}
+@anchor{client-substitute-urls}
+Consider @var{urls} the whitespace-separated list of substitute source
+URLs, overriding the default list of URLs of @command{guix-daemon}
+(@pxref{daemon-substitute-urls,, @command{guix-daemon} URLs}).
+
+This means that substitutes may be downloaded from @var{urls}, provided
+they are signed by a key authorized by the system administrator
+(@pxref{Substitutes}).
+
+@item --no-substitutes
+Do not use substitutes for build products. That is, always build things
+locally instead of allowing downloads of pre-built binaries
+(@pxref{Substitutes}).
+
+@item --rounds=@var{n}
+Build each derivation @var{n} times in a row, and raise an error if
+consecutive build results are not bit-for-bit identical.
+
+This is a useful way to detect non-deterministic builds processes.
+Non-deterministic build processes are a problem because they make it
+practically impossible for users to @emph{verify} whether third-party
+binaries are genuine. @xref{Invoking guix challenge}, for more.
+
+Note that, currently, the differing build results are not kept around,
+so you will have to manually investigate in case of an error---e.g., by
+stashing one of the build results with @code{guix archive --export},
+then rebuilding, and finally comparing the two results.
+
+@item --no-build-hook
+Do not attempt to offload builds @i{via} the daemon's ``build hook''
+(@pxref{Daemon Offload Setup}). That is, always build things locally
+instead of offloading builds to remote machines.
+
+@item --max-silent-time=@var{seconds}
+When the build or substitution process remains silent for more than
+@var{seconds}, terminate it and report a build failure.
+
+@item --timeout=@var{seconds}
+Likewise, when the build or substitution process lasts for more than
+@var{seconds}, terminate it and report a build failure.
+
+By default there is no timeout. This behavior can be restored with
+@code{--timeout=0}.
+
+@item --verbosity=@var{level}
+Use the given verbosity level. @var{level} must be an integer between 0
+and 5; higher means more verbose output. Setting a level of 4 or more
+may be helpful when debugging setup issues with the build daemon.
+
+@item --cores=@var{n}
+@itemx -c @var{n}
+Allow the use of up to @var{n} CPU cores for the build. The special
+value @code{0} means to use as many CPU cores as available.
+
+@item --max-jobs=@var{n}
+@itemx -M @var{n}
+Allow at most @var{n} build jobs in parallel. @xref{Invoking
+guix-daemon, @code{--max-jobs}}, for details about this option and the
+equivalent @command{guix-daemon} option.
