In that case, you can ofcourse use /etc/ld.so.preload which is honored
by setuid programs and has the advantage that it is system wide - no
need to jump through hoops to make sure LD_PRELOAD is set everywhere.

Usually libc itself uses __write() internally instead of write(), and
AFAIK you can happily replace those.
