 No, that way it works. I've just tried it out. If you bake the preseed into 
 the initrd, 
 anything works as expected.
 
 I've put the preseed.cfg to the root of the ISO and passed it by APPEND 
 settings to the kernel:
 neither file=/cdrom/preseed.cfg, nor file=/hd-media/preseed.cfg, nor 
 file=preseed.cfg works.
 
 Exactly the same style (using file=/cdrom/preseed.cfg) works for 
 net*installer*, but not
 for net*boot*.

AFIAIK the netboot mini.iso images are basically all the bits of PXE
boot, but in an ISO. As such there is nothing of interest (e.g. no
packages) on the ISO once the kernel + initrd are loaded and I wouldn't
necessarily expect it to bother trying to mount it in the installer
environment.

By contrast a netinst image includes the base system on the CD, so it
would be mounted.

 The funny thing: for self-built net*boot* images (about 10 MB), it works with 
 a seperated
 preseed.cfg outside initrd without a problem. But building the installer on 
 my own takes
 lots of dependencies... I wonder, what went wrong on the automatic build of 
 mini.iso :(

What do you mean by a outside the initrd? How are you self-building
these netboot images?

   If you bring up a console (e.g. Ctrl-Alt-F2) when having booted from the
 mini.iso, and check if the S35initrd-preseed file is in place.  My guess
 is that the mini.iso does not include initrd-pressed.udeb.

 Ah! Let me check:
 mini.iso gives me: ./lib/debian-installer-startup.de/S35initrd-preseed
 netinstaller is equal, even when looking for anything contaning
 preseed.

This makes a bit more sense (I was wondering how you could have avoided
the initrd-preseed stuff).

So, my next guess is that file-preseed is the udeb that is in the
netinst, but is not the mini.

If that's the case, you can probably just use network-preseed to get
the job done, but specifying it as a url=, rather than as a file=
like this:

  url=file:///cdrom/preseed.cfg

(the 3 slashes are required BTW)

BTW You can check my theory by looking for /var/lib/dpkg/info/file-preseed*

Cheers, Phil.
