It's an LD_PRELOAD hack. When glibc calls itself --- for example when fopen()
calls open() --- it does so using a hidden private interface, which means the
preloader library doesn't get a chance to override it. plasticfs wants a glibc
compiled with --disable-hidden-plt to expose this interface.
Or so the plasticfs docs say --- I'm sure this can be worked around, since
fakeroot and fakechroot manage it, but I wouldn't know how to do that. Also,
I'm working on the assumption that upstream at least know something about what
they're talking about...
