NAME¶

umfuse - User Mode FUSE implementation for umview

SYNOPSIS¶

um_add_service umfuse.so
umview ... --preload umfuse.so

DESCRIPTION¶

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

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.

  umfusexxxx -o options source mountpoint

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.
