John, many of use have huge time investments in /usr/local/lib and
/usr/X11R6/lib ports-derived libraries. While I'm definitely going to
be wanting to transition these to elf, I'd not wanted to have to do it
suddenly. How will this ldconfig change affect the fact that my elf
system still must use many aout libs (and probably will for some months
ahead)? Understand the point of this question isn't system libs, its
all the ports stuff, which just won't transition in one swell foop like
the system did.
