I think it is, running LVM and selecting logical view it looks as if 
root is /dev/kingston/root.

In the physical view root is described as linear mapping 83 extents.

To address my immediate problem of low disk space on root and given 
that root does appear to be on the lvm, I could do that now?

For example, shrink /home and reallocate the freed space to /root?

Would it be a problem if the new SSD is much smaller than the original 
HD?
