Right. This is the question I was trying to ask.
To amplify, suppose I have libc-2.1.3 installed, along with
libnss_compat-2.1.3.so, etc. If a daemon is started, and at some point
makes a name service call, then some libnss_*-2.1.3 module is loaded.
Now if new libc and libnss_* files are loaded onto the disk, why would
that change the behaviour of a running daemon? Would it not load the same
libnss_*-2.1.3 module as before?
