maintainer does check for /proc and fails gracefully in its absence.

      echo -n 'Generating mdadm.conf... ' >&2
      if /usr/share/mdadm/mkconf generate $CONFIG 2>/dev/null; then
        echo done. >&2
      else
        echo "failed (/proc probably not mounted)." >&2
        rm -f $CONFIG
      fi

and in mkconf:

      if [ ! -d /proc/$$ ]; then
        echo E: /proc not available. Exiting... >&2
        exit 2
      fi

Anyway, I am moderately certain that the bug is the same as #390756
and has thus been fixed in -7.

Wouldn't a lazy umount help?
