hi

I'd like to change some files in a bootable iso file.
Howto mount bootable iso file with write permission?

I've tried:

Code:

# mount -o loop my.iso /mnt
mount: warning: /mnt seems to be mounted read-only.
# umount /mnt 
# mount -o loop -rw my.iso /mnt
mount: warning: /mnt seems to be mounted read-only.

but still read only.

Is it only solution to copy these file and create a new iso file after changes, or perhaps xorriso?

ISO file-systems are per definition read only. So either you copy the files and create a new image or you use one of the tools that are able to change those images.
Mounting with write permissions is simply not possible.

Thx , but knows anyone if xorriso can do this?

I'm not familiar with xorriso

Follow the steps described in this linked page:

Take a look at the package "cdfs-src".

It may do what you want.
