Yes, indeed.  I'm aware of that.  I was just expressing the general
principle that you would want to combine the mv and the ln when moving
_any_ important subtrees.  I already said that I _would not move_ /lib
off the root filesystem, on a number of obvious general principles; the
fact that doing so breaks SO links (presumably unless you _also_ first
update /etc/ld.so.conf and run ldconfig) was interesting but academic.

Thanks, but I'd _greatly_ prefer to do any maintenance on that level of
invasiveness from separate maintenance media, for lots of reasons.

As I said, this whole thing is rather academic since moving /lib just
isn't the right solution in the first place, but surely one wouldn't be 
crazy enough to attempt such things on anything but a highly quiescent
system.
