dracut fails to build bootable initramfs on fc22

Yes, just an ext3 format. I've since learned it appears to be
necessary to have the USB stick inserted into the working system being
used to create the initramfs, or the module isn't copied into the
initramfs, therefore making it impossible to mount from the dracut
shell.

I've also just updated the system to 4.1.6-201.fc22.x86_64, and I
don't believe the USB stick was inserted at the time, yet the
initramfs contains usb-storage, so I really don't know for sure what's
going on.

I tried "dracut --add-modules usb-storage ..." but it says usb_storage
(with an underscore) it wasn't found. It sounds like the --add-modules
is for dracut modules?

I hope someone can help clarify the confusion with dracut modules and
kernel modules and why usb-storage is included while other times it's
not.

Thanks,
Alex
