The upgrade script should at least be consistent with the default /etc/rc.conf which still has /usr/lib/compat, /usr/X11R6/lib and /usr/local/lib. It's not clear that we will ever need a elf libraries in /usr/lib/compat. > So, the real question is: What is the ugprade script going to do?

Not just rc.conf. If ld.so and ld aren't both hacked, then all -Lfoo's in makefiles would need to be changed to -Lfoo/aout for the aout case but left alone for the elf case. All $LIBRARY_PATH's and $LD_LIBRARY_PATH's in files and environments would need to be changed similary. We don't even get this right for the paths in /usr/src/Makefile.inc1 (the paths there work for the wrong reasons). This shows that aout subdirectories should never have been used. Elf libraries should have been put in subdirectories. It would be relatively easy to move them to the right place later if this is planned for. Bruce
