Description of problem: 'chown rpm.rpm' should be replaced with 'chown rpm:rpm'. Obvious bad consequences if there is an rpm.rpm user name, and anyway the '.' syntax will go away eventually. Version-Release number of selected component (if applicable): 4.3-0.13
Is this change from rpm.rpm to rpm:rpm really necessary? It will create endless problems with spec files.
POSIX disallows it. The xxx.yyy syntax will go away eventually.
Fixed in rpm-4.4.3-0.24 when built.
