+Mount options
+~~~~~~~~~~~~~
+
+'fd=N'
+
+ The file descriptor to use for communication between the userspace
+ filesystem and the kernel. The file descriptor must have been
+ obtained by opening the FUSE device ('/dev/fuse').
+
+'rootmode=M'
+
+ The file mode of the filesystem's root in octal representation.
+
+'user_id=N'
+
+ The numeric user id of the mount owner.
+
+'group_id=N'
+
+ The numeric group id of the mount owner.
+
+'default_permissions'
+
+ By default FUSE doesn't check file access permissions, the
+ filesystem is free to implement it's access policy or leave it to
+ the underlying file access mechanism (e.g. in case of network
+ filesystems). This option enables permission checking, restricting
+ access based on file mode. This is option is usually useful
+ together with the 'allow_other' mount option.
+
+'allow_other'
+
+ This option overrides the security measure restricting file access
+ to the user mounting the filesystem. This option is by default only
+ allowed to root, but this restriction can be removed with a
+ (userspace) configuration option.
+
+'kernel_cache'
+
+ This option disables flushing the cache of the file contents on
+ every open(). This should only be enabled on filesystems, where the
+ file data is never changed externally (not through the mounted FUSE
+ filesystem). Thus it is not suitable for network filesystems and
+ other "intermediate" filesystems.
+
+ NOTE: if this option is not specified (and neither 'direct_io') data
+ is still cached after the open(), so a read() system call will not
+ always initiate a read operation.
+
+'direct_io'
+
+ This option disables the use of page cache (file content cache) in
+ the kernel for this filesystem. This has several affects:
+
+ - Each read() or write() system call will initiate one or more
+ read or write operations, data will not be cached in the
+ kernel.
+
+ - The return value of the read() and write() system calls will
+ correspond to the return values of the read and write
+ operations. This is useful for example if the file size is not
+ known in advance (before reading it).
+
+'max_read=N'
+
+ With this option the maximum size of read operations can be set.
+ The default is infinite. Note that the size of read requests is
+ limited anyway to 32 pages (which is 128kbyte on i386).
+
