This is a very minor bug report, and I'm not sure it even qualifies for a
bugzilla entry, but I'll file it for the sake of completeness.

Lines 33 and 35 of the NSD spec file read:

install -d 0755 %{buildroot}%{_initrddir}
install -d 0700 %{buildroot}%{_localstatedir}/run/%{name}

This causes 2 extraneous directories to be created in the build directory.

They should read:

install -d -m 0755 %{buildroot}%{_initrddir}
install -d -m 0700 %{buildroot}%{_localstatedir}/run/%{name}

This doesn't affect the package build, because the files section of the spec
file sets the permissions correctly. But I'm filing this anyway.
