I forget debconf details, but does this work for other settings for
you? I.e. are you sure that "seen false" doesn't cause it to ignore
the preseeded value and use the default anyway?

From the code, I do not understand how this is even possible:

    db_get mdadm/initrdstart
    INITRDSTART="${RET:-all}"

This means that INITRDSTART only gets initialised to 'all' if $RET
was not set. Either $RET is 'all', in which case debconf is at
fault, or there are gnomes in your PC.

Do you think you could try to reproduce this on a new machine in the following
order:

  1. use debconf-set-selections as you would
  2. use dpkg --unpack mdadm_*.deb to merely unpack the package
  3. change set -eu at the top of /var/lib/dpkg/info/mdadm.postinst to set -euvx
  4. insert echo $RET between the two lines of code shown above
  5. run dpkg --configure mdadm
  6 paste the output to me?
