Currently /usr/share/ucs-school-import/scripts/create_dc is a symlink to ucs-school-import, a legacy import script for all sorts of things, that does not use the ucsschool.lib. The ucsschool.lib contains the functionality to create school DCs, but it is used only by the UMC wizards. ucs-tests verify that both legacy code and ucsschool.lib code produce valid DCs. Remove the legacy script code and replace it with a cmdline tool that uses the ucsschool.lib code.
