Just curious, besides Mozilla software, are there other software components that rely on libnss ?

Yes, there's a discussion about it here:

http://lwn.net/Articles/428292/

It's part of the LSB and is also used by some quite high profile proprietary software packages.

Ok, fixed.

Hopefully the attached version will not be word wrapped. Unfortunately gmail makes it very difficult not to word wrap patches (I don't have SMTP access from behind the corporate firewall).

I've added some description to the patches.
