We should probably have lvm2 tools check the driver (and libdevmapper) version after processing arguments. So, after making sure the user doesn't just want to run vgchange --help, vgchange should check to make sure that a) there _is_ a version of dm in the kernel b) the version in the kernel is compatible w/ it This would lead to some better error messages, and hopefully less questions. Instead of: [dilinger@wax tools]$ sudo vgchange -a y No volume groups found Perhaps: [dilinger@wax tools]$ sudo vgchange -a y Error: device-mapper driver not found; support must be compiled into the kernel! [dilinger@wax tools]$ sudo vgchange -a y Error: the version of device-mapper in the kernel is incompatible with this lvm package; please upgrade device-mapper. Support is already in the kernel and libdevmapper for driver version querying; should be just an issue of adding the check to the lvm2 tools.
