Are you sure we need alternatives for something like libmpi_cxx.so.0 which
the 'other' (ie LAM) doesn't have?

AFAIK update-alternatives is for several implementations of the same file
only.

Or are you in fact suggesting to use update-alternatives for libmpi.so _and_
and the same time update all those libmpi_$Foo.so that only appear with Open
MPI ?  That, I guess, would still be correct use of alternatives via the
slave.  In fact there may or may not be exampel cases from the vi use or some
other u-a use.

Thanks for digging through this!
