That's not the reason, because install-info is supposed to replace the
old entries with the new ones (unless there's a bug in install-info).

I think the reason is that the section names used by the distributed
info/dir file are different from the section names stated by the
individual Info files.  Could you perhaps verify that?

Thanks.

However, isn't it better to invoke install-info with the --keep-old
option?  Does that solve the problem?
