It's by design that we fail the install if you've installed on a 
different device previously.  The cleanup is actually done in a dracut 
plugin to avoid issues with something holding locks on the filesystems 
we're cleaning up.  Because it's in dracut, it's not possible to include 
this in the installation progress.

You have a couple options for doing this cleanup if you're doing an 
install to a different device.

1.  manually do the cleanup
2.  specify "uninstall storage_init=/path/to/device"

uninstall will wipe the devices in storage_init, the proceed with the 
install.

As indicated above, you can use "reinstall" if you're installing to the 
same device you previously installed to.
