a separate mount name space, its own PID name space, network name space,
etc. This helps achieve reproducible builds (@pxref{Features}).
+When the daemon performs a build on behalf of the user, it creates a
+build directory under @file{/tmp} or under the directory specified by
+its @code{TMPDIR} environment variable; this directory is shared with
+the container for the duration of the build. Be aware that using a
+directory other than @file{/tmp} can affect build results---for example,

+sockets might hit the name length limitation for @code{sun_path}, which
+it would otherwise not hit.
