You still seem to be missing the correct syntax. (note: this might not solve your problem, and even issuing the right command might be of no help, but since you asked for it, here it is). With every mount command, you have to specify at least two things: *what* to mount, and *where* to mount it, in this order. *Where* is usually a path to some (preferably empty) directory. *what* can be various things, depending on what you're trying to mount. For regular disk partitions, it's usually a device file (eg, /dev/sda1). For NFS, it's a string of the form remote_host:/remote/path. For loopback filesystems (ie, filesystems contained in a single file), it's the name of the container file, like your /tmp/r1. When mounting loopback filesystems, the "-o loop" option must be given. The "-o loop" option accepts some optional parameters. One of these is the specification of the loopback device that should be used. To explicitly specify a loopback device, use "-o loop=/dev/loopX". If no loopback device is specificed, then mount will automatically pick an unused loopback device (probably /dev/loop0). Your command # mount -t vfat -o loop /dev/loop2 /tmp/r1 uses an incorrect syntax for the specification of the loopback device (which is optional anyway), and does not tell where to mount the filesystem. So, what you probably want is # mount -t vfat -o loop=/dev/loop2 /tmp/r1 /mnt/somewhere or just simply # mount -t vfat -o loop /tmp/r1 /mnt/somewhere -- [EMAIL PROTECTED] mailing list
