Indeed, checking the initrd you mentioned I see the iso-scan and load-iso
packages available, while in the initrd from current image
it is not.

Indeed.

It is strange that the changelog of debian-installer in *not*one*word*
mentiones that iso-scan got lost ... maybe I am hallucinating and
didn't install my laptop in the way I thought I did ;-)

Not necessary, a simple
iso-scan/filename=$isofile iso-scan/ask_second_pass=true
added to the cmd line works.
That means, one *only* needs to replace the initrd. My grub.cfg
entries now look like:
set isofile="/boot/iso/firmware-8.0.0-amd64-i386-netinst.iso"
menuentry '64 bit Install' {
set background_color=black
loopback loop (hd0,1)$isofile
linux (loop)/install.amd/vmlinuz iso-scan/ask_second_pass=true
iso-scan/filename=$isofile vga=788 -- quiet
initrd /boot/debian/install.amd/initrd.gz
}
So the kernel is taken from the iso image, only the initrd is replaced.
Probably the safest option is to use *NOT* the initrd from the daily
builds, but from the release.
I will update the blog later on, now I have a meeting.
Big thanks for the information!!!
Norbert
