add/remove files to an ISO image and save the changes to the same iso file.
Posted on 2006-04-08
Is there a way to mount a CD/DVD ISO image as writable filesystem?
Or is there a software like Winiso or Magiciso for linux able to to that?
My goal is to add or remove some files to an ISO image without recreating the entire ISO image from scratch. I know that I can copy the entire contents of the iso image in a directory, add the files and then recreate the iso image, but this takes too much time and it's not efficient at all. With Winiso or Magiciso (for Windows) I simply open the file, add/remove something, save. The file is saves in a second (it is not rewritten entirely). Is there a software like this for linux? Even non-free.
The perfect solution would be to mount the iso as writable... but I couldn't achieve this.
If I do (as root): mount -o loop -t iso9660 filename.iso /mnt/iso
the /mnt/iso looks like writable, but if I try to write something inside I get:
touch: cannot touch `/mnt/iso/test': Read-only file system
I tried also: mount -o loop,rw -t iso9660 filename.iso /mnt/iso
it is still readonly...
I'm using Ubuntu Linux, kernel-image 2.6.12-10-k7. But if you tell me that there is a patched module or writable support in a new kernel it's not a problem for me to recompile it and try. Just let me know ;-) Thanks.
