You probably disabled CAPABILITIES. (CAPABILITY_MODE is probably not required
for *this* but will be necessary for Firefox content process sandboxing which
I'm working on right now, so I recommend enabling that as well.)

I guess everything in base is still built to handle kernels without
CAPABILITIES and there's not that much software out there leveraging it yet,
but it's a weird thing to disable. It's public API for programs, it really
shouldn't even be optional at this point, the cap_rights_limit(2) manpage
doesn't even mention ENOSYS like cap_enter(2) does.
