Taking my example above, x.rpm is not supplied by any repository;
then, a simple method to install it is

yum localinstall x.rpm

With this procedure, I will know the dependencies, which I will install before

rpm -ihv x.rpm

as "yum localinstall" is not able to install x.rpm due to the fact
that x.rpm is not signed.
