Any chance you can you describe more in detail how you start
unionfs-fuse? Directly within the initramfs (if so, could you please
tell me exactly how)? Or using
/usr/share/doc/unionfs-fuse/examples/S01a-unionfs-fuse-live-cd.sh as
link in rcS.d? We just have a 3 day weekend ahead and there might a good
chance I can fix whatever your problems are... But it would be good if I
could reproduce it somehow. I think for the following mails we should
also drop most CCs here, as it is kernel unrelated.
Thanks,
Bernd
