Thanks for the info!

I tried to hack debian-installer, and split orion5x flavour into
orion5x and orion5x-qnap.
For orion5x-qnap, I removed a few qnap unused stuff in "pkg-lists" folder.
I pushed my change to branch "split_orion5x"
  - https://anonscm.debian.org/cgit/d-i/debian-installer.git/log/?h=split_orion5x

Here's comparison of error build log from debian-installer:

  branch master:
  File size 4465504 is larger than total, padded size 4194304.

  branch orion-qnap (after my change):
  File size 4394588 is larger than total, padded size 4194304.

so the qnap d-i image has reduced 70k, and need another 200k reducement.

I have no idea whether this kinda change valid.
Maybe it's just proof of concept that size can be reduced.
