Has anybody every installed Oracle software without using the OUI?

I use this command and it still tries to launch the OUI, how come.

./runInstaller -silent -noconfig -responsefile `pwd`/db_install.rsp

Your platform requires the root user to perform certain pre-installation
OS preparation. The root user should run the shell script 'rootpre.sh' before
you proceed with Oracle installation. rootpre.sh can be found at the top level
of the CD or the stage area.
Answer 'y' if root has run 'rootpre.sh' so you can proceed with Oracle
Answer 'n' to abort installation and then ask root to run 'rootpre.sh'.
Has 'rootpre.sh' been run by root? [y/n] (n)
