Yes.

This makes sense but the reason the libnfsidmap-devel package is not
be upgraded (or installed) is because:

dnf install /tmp/libnfsidmap-devel*
Last metadata expiration check: 0:10:48 ago on Fri 27 Oct 2017 11:19:35 AM EDT.
Error: 
 Problem: conflicting requests
  - nothing provides libnfsidmap = 2.2.1-0.fc28 needed by libnfsidmap-devel-1:2.2.1-0.fc28.x86_64

even though libnfsidmap-2.2.1-0 is installed. 

The problem is caused by the Requires: in the libnfsidmap-devel subpackage

%package -n libnfsidmap-devel
Summary: Development files for the libnfsidmap library
Group: Development/Libraries
Requires: pkgconfig
Requires: libnfsidmap = %{version}-%{release}
^^^^^^^^^^^

Now if I remove the '%{version}-%{release}' the package 
is installed/upgraded... but seems wrong to me
the -devel should be tied to a particular version, right?

Plus this was the way it was in the original libnfsidmap rpm.
