Description of problem:

In ./install.pl --help, clear-db flag says 

    --clear-db
            Clear any pre-existing database schema before installing. This
            will destroy any data in the Satellite database and re-create
            empty Satellite schema.

but when you try using it, it says:

# ./install.pl  --clear-db
* Starting the Red Hat Network Satellite installer.
* Performing pre-install checks.
* Pre-install checks complete.  Beginning installation.
* RHN Registration.
** Registration: System is already registered with RHN.  Not re-registering.
* Checking for uninstalled prerequisites.
* Applying updates.
* Installing RHN packages.
* Now running spacewalk-setup.
* Setting up Oracle environment.
* Setting up database.
The embedded database appears to be already installed. Either rerun
this script with the --skip-db-install option, or use the
'/usr/share/spacewalk/setup/oracle/remove-db.sh' script to remove the embedded database and try
again.

First --skip-db-install is not the right suggestion as I already know that there is a db I want to wipe and hence trying to use --clear-db. I guess the --clear-db should call remove-db.sh and do the needful. Instead of asking the user to run another script.
