"rm_work", see the :ref:`ref-classes-rm-work` class in the
Yocto Project Reference Manual.
When you inherit this class and build a ``core-image-sato`` image for a
``qemux86-64`` machine from an Ubuntu 22.04 x86-64 system, you end up with a
final disk usage of 22 Gbytes instead of &MIN_DISK_SPACE; Gbytes. However,
&MIN_DISK_SPACE_RM_WORK; Gbytes of initial free disk space are still needed to
create temporary files before they can be deleted.
