The gai.conf file is installed with the following attributes:

%attr(0644,root,root) %verify(not md5 size mtime) %ghost %config(missingok,noreplace) /etc/gai.conf

Given "not md5 size mtime", the rpm verification should not print "5" at all.

This looks like an rpm bug?

I think I see what you're trying to say. In that the gai.conf is double listed in glibc and glibc-common. Let me verify.

OK, I verified the spec file and I still don't see a problem.

glibc owns /etc/gai.conf and has attributes for it that should properly account for it being a conf file, just like it owns /etc/ld.so.conf and /etc/nsswitch.conf.

If you still see a problem please specify it in more detail.

Please test on rhel6, there it will show the problem.

Note that the pseudo-patch is to remove the file gai.conf
from rpm.filelist, so that it will be owned by glibc-common.

The example in the original bug report is that the problem
does not happen if one customizes nsswitch.conf.

01448083.spec

This simple spec tries to show the point :)

Just build and install it, then add some contents to
/etc/gai.conf.01448083

and sample test:

[pcpa@rhel-6-6-x86-64 rpmbuild]$ /bin/rpm -V 01448083 --nodigest --nosignature --nolinkto --nosize --nouser --nogroup --nomtime --nordev --nocaps --nomode
..5......    /etc/gai.conf.01448083
[pcpa@rhel-6-6-x86-64 rpmbuild]$ /bin/rpm -V 01448083-common --nodigest --nosignature --nolinkto --nosize --nouser --nogroup --nomtime --nordev --nocaps --nomode
[pcpa@rhel-6-6-x86-64 rpmbuild]$ rpm -qf /etc/gai.conf 
glibc-2.12-1.164.el6.x86_64
glibc-common-2.12-1.164.el6.x86_64
glibc-2.12-1.164.el6.i686
[pcpa@rhel-6-6-x86-64 rpmbuild]$ rpm -qf /etc/gai.conf.01448083 
01448083-1-1.el6.x86_64
01448083-common-1-1.el6.x86_64

A minor change I forgot to do "in the last minute"
to the sample is:

-%files -f rpm.filelist
-/etc/%{name}
-/etc/gai.conf.%{name}
+%files -f rpm.filelist

But it will show the problem either way. Just that
the latter would better mimic glibc.spec.

Why not make rhel-6 match rhel-7?

That is fine as well. But I still suggest adding
gai.conf after nsswitch.conf in the regex that remove
config files from rpm.filelist.

Otherwise, it is kind of relying on undefined
behavior. i.e. file listed twice, once as a normal
file, and once as a "special" file.
