having done that while something's mounted on /mnt/fda, they're changing the permissions of the root dir in the mounted filesystem itself. That could actually be important if something other than root is trying to read them later.
The -o loop in the latest instructions is actually unnecessary -- you already set up a loop device by hand with losetup, you don't need to set up another! If you'd left both parameters off instead of one, it would've worked.
hey, i just found this forum...how cool.

Hi,
I have a windows emulator that I am wanting to try out, but my Windows 3.1 files are split up over 6 .DSK images, and I need to convert them to an .IMG that I can actually mount on my system (so that the emulator can see it).
Is there a way to do this?
thanks.

losetup
LOSETUP(8) MAINTENANCE COMMANDS LOSETUP(8)NAME
losetup - set up and control loop devices
SYNOPSIS
losetup [ -e encryption ] [ -o offset ] loop_device file
losetup [ -d ] loop_device
DESCRIPTION
losetup is used to associate loop devices with regular files or block devices, to detach loop devices and to query the status of a loop
device. If only the loop_device argument is given, the status of the corresponding loop device is shown.
OPTIONS -d detach the file or device associated with the specified loop device.
-e encryption
enable data encryption. The following keywords are recognized:
NONE use no encryption (default).
XOR use a simple XOR encryption.
DES use DES encryption. DES encryption is only available if the optional DES package has been added to the kernel. DES encryption
uses an additional start value that is used to protect passwords against dictionary attacks.
-o offset
the data start is moved offset bytes into the specified file or device.
RETURN VALUE
losetup returns 0 on success, nonzero on failure. When losetup displays the status of a loop device, it returns 1 if the device is not con-
figured and 2 if an error occurred which prevented losetup from determining the status of the device.
FILES
/dev/loop0,/dev/loop1,... loop devices (major=7)
EXAMPLE
If you are using the loadable module you must have the module loaded first with the command
# insmod loop.o
The following commands can be used as an example of using the loop device.
dd if=/dev/zero of=/file bs=1k count=100
losetup -e des /dev/loop0 /file
Password:
Init (up to 16 hex digits):
mkfs -t ext2 /dev/loop0 100
mount -t ext2 /dev/loop0 /mnt
...
umount /dev/loop0
losetup -d /dev/loop0
If you are using the loadable module you may remove the module with the command
# rmmod loop
RESTRICTION
DES encryption is painfully slow. On the other hand, XOR is terribly weak.
