For apitrace we ended up using the $LIB dynamic expansion to let the

That's presumably applicable to fips and vogl also.
Yes, that $LIB thing is really convenient for this.. The last time I
looked, it wasn't available within LD_PRELOAD like it is for
LD_LIBRARY_PATH.
But yes, we already are using this in vogl and fips where possible.
Aha! But if you prepend /usr/lib/$LIB/vogl/ to LD_LIBRARY_PATH and then
set
LD_PRELOAD to vogl.so (or whatever, rather than the absolute path) then
you
effectively get it for LD_PRELOAD, too :)
The only edge case I can think of that this would break is where the
tracee
itself prepends a path containing a _different_ vogl.so to
LD_LIBRARY_PATH;
that seems like a pretty unlikely confluence of events.
