Better to check for the new 'lvm' base command: other commands are
links to it: check that running 'lvm version' produces complete output.
That will also confirm that device-mapper is available in the live
kernel and that /dev/mapper/control is set up correctly.
(See device-mapper/scripts/devmap_mknod.sh)

It's better to check for that in /proc/misc, which will tell you whether
or not device-mapper support is present in the running kernel.

Better to attempt to load the module with modprobe and then do the
tests above to check it worked.
