Just copying /sbin/lvm2 to some other (non root) lvm does not do the 
job for me. Even if it worked it seems to be an ugly workaround. 

The question is, if there are plans to change the snapshot capabilities
of lvm2 in a way, that makes it possible to create snapshots even if the
tools reside on the lvm.
