Since jenkins uses "schroot -c source:" everywhere, probably nothing, as
that effectively works around the "union-type" schroot configuration.

Probably, it would be better to only use the source chroots when
updating the chroot, and make sure the union-type works correctly for
other cases. Alternately, dropping the union-type configuration and
acknowledging that these are plain directory chroots would make sense.

But that's for another patch series...
