It=E2=80=99s an environment variable making ld.so preload dynamical librari= es=20 before any other, so that you can overwrite any C function with another,=20 just by specifying a .so library implementing it in that variable. You=20 can use that to tweak the behavior of any program. Lars was using that as= =20 an argument to state it is futile to stop users from running proprietary=20 software if they want to since they can do it anyway that way. I agree the issue is not stopping users, but making them run such software= =20 anyway, whatever their specific will regarding emacs.
