I cannot really provide a generic reproducer, but I'm these days
upgrading lots of servers and I now the third time observed something
strange:

|    warning: /usr/opkg/.bash_login created as /usr/opkg/.bash_login.rpmnew
|    warning: /usr/opkg/.bashrc created as /usr/opkg/.bashrc.rpmnew

This is during e.g. upgrading the RPM 5 package "openpkg-4.0a0-20080412"
to "openpkg-4.0a0-20080413" (the difference is just a small typo fix,
everything else is the same in the package!). And now let's look at the
%config files which produced the warnings:

As you can see, no content change, no permission changes, nothing (sure,
as I said, only a typo in a completely different edge of the packaging
was fixed, everything else remained the same). Nevertheless RPM 5
thought there was a conflict and produced .rpmorig or .rpmnew files for
all(!) %config files in the package. The first time I observed this, I
still thought: "well, strange, but perhaps there was really a conflict".
But now I'm not than surprised: there is really no difference, but
nevertheless RPM 5 thinks it is.

Does anybody has a clue what happened here?

All this is with RPM 5.1b2, BTW!

For one installation I currently even can reproduce the problem:

| # /usr/opkg/bin/openpkg rpm -V openpkg
| S.5....T  c /usr/opkg/etc/rc.conf
| # /usr/opkg/bin/openpkg rpm -Uvh /usr/opkg/RPM/PKG/openpkg-4.0a0-20080413.amd64-freebsd7.0-opkg.rpm --replacepkgs

Isn't this strange? Verify says what I expect: only one file is changed.
But on the next installation (here even of the _same_ package, but
it also happens on real upgrades AFAIK), the %config files are all
considered in conflict...
