[PATCH] Comment on the need for Provides: nss_db.

[Carlos O'Donell]

In F16 Fedora and RHEL 6 there was an nss_db package which used the Berkely DB
format for the database. This package was deprecated in favour of the builtin
nss_db support in glibc. In order to make the rpm dependency transition easier
we should either Provides: nss_db in glibc.spec or provide a nss_db package which
can be installed to provide the nss_db functionality. Today in Rawhide we provide
a subpackage. This patch adds a comment to ensure we understand that transition
and assist where we can in making that smoother.

* Mon May 21 2018 Carlos O'Donell  - 2.27.9000-19
- Ensure that nss_db subpackage or Provides: nss_db exist for legacy upgrades.

OK for Fedora Rawhide?

You are changing a comment only, so this change doesn't ensure anything. 
  I suggest to skip the %changelog and Release: updates for this change.

Thanks,

Sounds good. I'll just alter the comment then :-)
