[tex-live] Problems with local /texmf on ntfs

[Felix Kupprat]

Dear everyone! I have the following problem customizing my texlive 
installation:
I want to include a personal texmf directory that lies on a ntfs 
partition that is not the partition of the texlive installation. The 
installation-path is /usr/local/texlive/
I have added the path to the custom directory to 
/usr/local/texlive/2008/texmf.cnf:

TEXMFDATEN = /media/Data/Dateien/miktexpersonal//
TEXMF = 
{$TEXMFCONFIG,$TEXMFVAR,$TEXMFDATEN,$TEXMFHOME,!!$TEXMFSYSCONFIG,!!$TEXMFSYSVAR,!!$TEXMFMAIN,!!$TEXMFLOCAL,!!$TEXMFDIST} 


This solution does not work completely. The file 
./miktexpersonal/bibtex/bst/biblatex/biblatex.bst is found running tex 
using the biblatex package.
However, the files 
./miktexpersonal/tex/latex/biblatex/bbx/authoryear.bbx and the custom 
style ./miktexpersonal/tex/latex/dai/bbx/dai.bbx can not be found.

Copying the whole folder like it is to my home directory and modifying 
the entry in the texmf.cnf everything works fine. I have tried various 
debug-commands that I found in the kpahsea-documentation, but they 
didn't actually help me (for a post of the output and discussion (in 
german) see http://www.golatex.de/viewtopic,p,10756.html#10756).

As everything works fine with the same directory-structure in my 
home-directory, I suppose that there is some incompatibility with the 
ntfs format of the other partition. Files are not compressed and don't 
make problems under Linux. Has anyone any idea what I have done wrong or 
how I can solve the problem? Tank You!

System Information:
Ubuntu 9.04
texlive 2008
editor: Lyx 1.6.2

Why I want to do this? I have a MikTeX 2.7 installation and Windows XP 
on the same system and want to use the same custom texmf on both 
systems. As Windows doesn't read the EXT partition of the linux 
installation, the directory has to be put on a windows-compatible partition.
