Yes, 'mostly'. You *will* need to 'make obj' beforehand, but IIRC most
everything will only write to obj when compiling. A noticeable exception
are the kernels (but you could always symlink /usr/src/sys to somewhere
appropriate).
For a better idea, how about one of the 'remove duplicates by
hardlinking them together' packages? It would allow you to have
essentially identical trees without wasting more than some inodes. Other
variations on this theme are possible, like lndir(1).
