The file /etc/fuse.conf allows for the following parameters:
- user_allow_other - Using the allow_other mount option works fine as root, in order to have it work as user you need user_allow_other in /etc/fuse.conf as well. (This option allows users to use the allow_other option.) You need allow_other if you want users other than the owner to access a mounted fuse. This option must appear on a line by itself. There is no value, just the presence of the option.
- mount_max = n - this option sets the maximum number of mounts. From the source code (2.4.1) it appears that it must be typed exactly as shown (with a single space before and after the equals sign).
As I noted above syntax requirements appear to be pretty finicky.
