umfuse - User Mode FUSE implementation for umview


um_add_service umview ... --preload


umfuse is the user-mode implementation of virtual FUSE filesystems for umfuse. When this service module is loaded it is possible to mount umfuse file systems. FUSE and umfuse are source level compatible, it is possible to compile a FUSE file system implementation as a dynamic library. The name of umfuse file system implementation libraries must begin with umfuse. Umfuse implemented file system are mounted and umounted by the standard utilities mount(8) and umount(8). Example: $ mount -t umfuseext2 /path/to/file.img /mount/point ... $ umount /mount/point The mount command for umfuse file systems allows some specific options: debug give a verbose feedback of each operation on the virtual file system. fuseuid=uid specify the effective uid for the operation on the virtual file system fusegid=gid specify the effective gid for the operation on the virtual file system human umfuse is default mode is omnipotent, i.e. the user acts as root in the mounted file system. When a file system gets mounted with the human option, access control is enforced. umfuse modules main program invocation options. umfuse calls the main program of the module with the standard syntax: umfusexxxx -o options source mountpoint Sometimes FUSE modules have been designed to accept a different syntax. It is possible to match the calling syntax by using the follwing options. nosource No image file should be specified. pre=string The string contains parameters that must be put before "-o options" post=string The string contains parameters that must be added at the end format=string This is the most powerful rewriting rule. If the main needs a completely different structure format can be used: the format string is similar to that used in printf. %O %S %M descriptors are substituted in the call as follows: %O=-o options, %S=source, %M=mountpoint. showcall Show the call syntax before the actual call. Use it for debugging.
