Howto mount iso as non-root user

[psy_ill]

I've seen this topic on other threads, but noone solved it exactly as I think it should be done, so here comes the full procedure:

1. Make sure you have enabled the loopback device in kernel
   
2. If you choose to compile the loopback device as a module, you need to make sure it loads at bootup
   
3. Add the following rows to your /etc/fstab:
   

   Code:

   # To mount .iso-files /tmp/cdimage/tmp.iso    /mnt/iso    iso9660    noauto,ro,user,loop    0 0

   
   
4. Create the directory /tmp/cdimage
   
5. Put the following two scripts somewhere in your $PATH:
   isomount.sh
   

   Code:

   #!/bin/bash MOUNTFILE="$1" # Convert relative paths to absolute MOUNTFILE=$(cd `dirname "$MOUNTFILE"` && pwd)"/"`basename "$MOUNTFILE"` MOUNTLINK="/tmp/cdimage/tmp.iso" ln -sf "$MOUNTFILE" "$MOUNTLINK" mount "$MOUNTLINK"

   
   isoumount.sh
   

   Code:

   #!/bin/bash MOUNTLINK="/tmp/cdimage/tmp.iso" umount "$MOUNTLINK" rm "$MOUNTLINK"

   
   
6. Set the file mode for the scripts so that you can execute them
   

Done! With the command

nice try, but how does it work when two users mount iso at the same time?

Since /tmp has the sticky bit set, only the user who created the softlink can remove it. So it does not matter if another user tries to create the softlink before the mounting fails, the softlink creation will fail too.

It will be like when another user tries to mount a cd which is already mounted. I understand your opinion though, because a cd must be considered as one limited resource but different iso-files should be mountable at the same time. It's still hard though to create mountpoints on-the-fly in /etc/fstab.
