Forcing use of nscd is a non-starter at many sites. Aside from cache
staleness issues, and nscd's well known instability, there's also the
issue that nscd doesn't intercept get*ent enumerations so things will
still crash depending on which nsswitch functions an app calls.
It would make sense to us
This additional patch fixes the crash in bug#1013798.

I'd be happy to write a patch for the documentation. And given all of

Right, given the timing for the Lucid release it's probably way too
