The Revert button (ubiquity UI) or "Undo changes" (debian-installer UI) do not recursively remove create device mapper nodes created with partman-crypto configure or activate menu items. LVM is not affected as much, as one can manually remove volume groups using the lvm menu. Further checking is needed what happens with partman-md during undo.
