Problems with jail mode

[Bertalan Fodor]

Hi, I set up a separate filesystem, running lilypond in jail mode.
My problem is that the last step, the PDF creation fails:
gs   -dSAFER  -dDEVICEWIDTHPOINTS=595.28 -dDEVICEHEIGHTPOINTS=841.89  
-dCompatibilityLevel=1.4  -dNOPAUSE -dBATCH -r1200  -sDEVICE=pdfwrite 
-sOutputFile="./test.pdf" -c .setpdfwrite -f "test.ps"' failed (32512)

But if I call this command with
sudo chroot /mnt/lilyloop gs   -dSAFER  -dDEVICEWIDTHPOINTS=595.28 
-dDEVICEHEIGHTPOINTS=841.89  -dCompatibilityLevel=1.4  -dNOPAUSE -dBATCH 
-r1200  -sDEVICE=pdfwrite -sOutputFile="./test.pdf" -c .setpdfwrite -f 
"test.ps"

that is, in a separate chroot, this creates the PDF.

Do you have any idea what is that 32512 error?

Thanks,

Bert
