Hi,

I have not looked at Tux3 for a long time, but there seems to be
a simple fix for at least this problem, and two workarounds:

1) Run the program in foreground (-f):

sudo ./tux3fuse tux3.img /mnt/zeit -f

2) Use absolute path for image file:

sudo ./tux3fuse $(pwd)/tux3.img /mnt/zeit

The following patch should hopefully fix this for good.

commit efc0cf49f6dd00dfbb84e88336d2c5d147a09ed0

Use absolute path for volume name

If fuse_daemonize() puts us into background it also switches our
working directory to '/', breaking the use of relative paths.

This patch fixes the problem by converting the relative path to
an absolute one.
