from the install root, not from the build host's filesystem.

==========================
Lorax now supports creation of product.img and updates.img as part of the build
process. This is implemented using the installimg command which will take the
contents of a directory and create a compressed archive from it. The x86, ppc,
ppc64le and aarch64 templates all look for /usr/share/lorax/product/ and
/usr/share/lorax/updates/ directories while creating the final install tree. If
there are files in those directories lorax will create images/product.img
and/or images/updates.img
process. This is implemented using the installimg template command which will
take the contents of a directory and create a compressed archive from it. The
directory must be created by one of the packages installed by
runtime-install.tmpl or by passing ``--installpkgs <pkgname>`` to lorax at
runtime. The x86, ppc, ppc64le and aarch64 templates all look for
/usr/share/lorax/product/ and /usr/share/lorax/updates/ directories in the
install chroot while creating the final install tree. If there are files in
those directories lorax will create images/product.img and/or
images/updates.img
These archives are just like an anaconda updates image -- their contents are
copied over the top of the filesystem at boot time so that you can drop in
