Another dash/bash problem on Debian or Ubuntu. I used the "source" 
command to load a script in the current shell, and presumably this is 
not POSIX, so dash (the default /bin/sh since last year) refuses it. 
Does anyone know the POSIXly correct way?

Anyway, fixed.

By default, fuse doesn't let user A view content in a file system 
mounted by user B. Even when A is root. It's an interesting security 
problem: the fuse daemon (running as user B) would get to see data 
belonging to A, without A having agreed to permit that.

There's an allow_other option:

./start_duggfs.sh /tmp/duggfs -o allow_other

but it's only available if you enable user_allow_other in /etc/fuse.conf 
(a file which doesn't exist by default and the format of which is not 
documented as far as I know).

To summarize, you should use the same account to mount duggfs and to 
explore its contents.
