thanks a lot for your kind suggestion!

Until now i was not aware about the existence of cloud-init, and after
getting slightly acquainted with it, i don't think this is useful at all
for my use case.
At the expense of appearing ignorant, but cloud-init appears to be an
overcomplicated approach for the basic purpose of running a simple
script during installation. Most probably, cloud-init is the perfect
soluion in other contexts than installing with an ISO to disk. In
comparison to the straight forward preseed/late_command ability of
debian-installer, cloud-init appears to be overkill for such simple needs.
My project[1] is designed to be used mostly offline and the
preseed/late_command feature is the perfect solution for running
arbitrary scripts in the limited context of the installer. This already
works absolutely fine with amd64/i386 since many years, and only the
recent addition of an arm64 variant brought up the complications we are
currently dealing with.
Thanks a lot!
Paul
