USB booting :: Mount sda1 and hda3 on start-up

This should be an easy question .. I would like to mount sda1 and hda3 on start-up.

I assume that I just to write:

mount /mnt/hda3
mount /mnt/sda1

In a start-up script. If so, which is the correct file to use.

I'd try /opt/bootlocal.sh. I'm not up to speed on USB, this works on frugal HD install.
