[lug] Reverse LD_PRELOAD?

[Davide Del Vento]

Never load would not make any sense. If your application is linked
against it (or loads it with dlopen), it needs it. If it does not need
it, it's a bug in your application.
If it does need it, but you have another version that you want to use,
either use LD_PRELOAD and/or LD_LIBRARY_PATH and/or RPATH.
