This will tell if the program is different and works on any RPM
based system regardless of their package contents.

rpm -V `rpm -qf /bin/login`

Or of you're not lazy as I am.

rpm -qf /bin/login # gets the name of the package
rpm -V util-linux # the name of the package returned.

A man who would consider himself a bandit if, pistol in hand, he
prevented me from carrying out a transaction that was in conformity with
my interests has no scruples in working and voting for a law that replaces
his private force with the public force and subjects me, at my own
expense, to the same unjust restrictions. -- Bastiat, Frederic, Harmonies
