Hi list,

I need to change one file in an existing ISO image. It is a DVD image btw.
Unfortunately I dont have many options of changing the fie before creating
the image.

Mounting is not the issue, copying data neither but the ISO is also
bootable. There must be a simpler solution as in copying all the content
with cpio and making it bootable. OS on the DVD is WinPE btw.

Does anyone have some pointers for performing this action?

Have you tried mounting it as a vnode ? and mounting it R/W ?

mdconfig -a -t vnode -f file.img
mount -t <type> /dev/md0 /mnt/rw_dvd

Where <type> may be cd9660 or some other format of the image.

I haven't seen reported success with this method (checked with various google searches), but perhaps there's something along these lines *will* work.

Hope that helps,
