device-mapper module in install kernel

Hi, Am I right thinking that kernel from CRUX 2.7 iso missing device-mapper module, therefore you cannot install distribution on the LVM2 based disk? I have created physical volume and volume group, but not succeed with logical volume. lvcreate complains on lack of device-mapper.
