Some admins shoot themselves into the feet with these options.

While --nodeps may really be necessary to ignore dependencies and upgrade
a package without any bad consequences (because some dependencies are not
future-proof and too strict), --force is short for "--replacepkgs
--replacefiles --oldpackage". The --replacefiles option is particularly
nasty and can cause bad trouble. Why? From the manual:

  --replacefiles
      Install the packages even if  they  replace  files  from  other,
      already installed, packages.

This will show up in "rpm -Va". But finding out where and what it breaks,
is left as an exercise.
