Sorry; I forgot about "shared/ask_device=manual". > To get rid of the thorough scan question Pascal's advise of boot option > "iso-scan/ask_second_pass=true" is in place. > > So overall string of kernel boot options would be like > "iso-scan/ask_second_pass=true shared/ask_device=manual > shared/enter_device=/dev/disk/by-label/<label>" > ouch, a bit long of boot options, but with this installer at least goes a > bit smoother... > > But still the question about boot opton "iso-scan/filename"... why isn't it > actually working? > What does it mean that this may be an output instead of an input?

It works for me when the ISO, vmlinuz and initrd.gz are all in /boot. -- Brian.
