I believe that SunOS does not have this problem. The procedure
for crashing SunOS is to first dump core into the swap space. After
successfully writing to swap, it attempts to find a place on any of
the mounted partitions which will facilitate the core file. If it
does find a place, it will then copy the core file from swap to that
area. I don't think that symlinks have anything to do with this.
