Thanks for report, but "/mnt" is directory for mounts and not the directory, where you should directly mount. I already had discussion with rpm guy - Jindrich Novy - about similar issue - see https://bugzilla.redhat.com/show_bug.cgi?id=526368 for details.

It is expected that rpm update should fail when one or more of the package
files/dirs are not installed due to read only target filesystem. Any other
behaviour could lead to incomplete package update, imagine package update on
filesystem with read only /usr. Maybe error from rpm could be more
comprehensive to allow user better address the issue. But this could be only
suggested as RFE for rpm. Feel free to make a suggestion there.

Closing NOTABUG.
