Could you tell us what's the proper soname naming
convention in LSB?

The two examples you gave, libc.so.6 and
libglib-2.0.so.0, clearly follow different naming
conventions.  I am only familiar with the libc.so.6
convention, which I believe comes from Unix
SVR4 as Howard Chu mentioned.

Getting back to the Debian libnss3.so.1d soname:
there are actually two issues:
1. Why Debian used libnss3.so.0d originally.
2. What Debian considers to be incompatible
changes in NSS 3.12 to change the soname to
libnss3.so.1d.

We are especially interested in the answer to the
second question.
