Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I want to modify bsdinstall scripts of FreeBSD 9.0 iso file. I simply extracted it and then recreate iso file but it didn't work. Then I discovered ISO Master for modify it without extraction but I got this error when I try to open It.

Failed to read directory tree: 'Rockridge filename missing when expected on image'

Why do I get this error? Also is there any other way to modify it without brake its boot ability?

I'm not sure this is really off-topic. It's presumably about how to remaster an ISO image using Ubuntu. I've posted this meta question, if anyone has any thoughts about that. –  Eliah Kagan Jun 19 '12 at 7:01

I`m going out on a limb

I have used Power ISO for Linux, and been happy with it. You can Download it Here

Usage: poweriso [parameters] [-switches]



List files and directories in image file.

Example: List all files and directories in root direcory of /home/sam/test.iso .
Command: poweriso list /home/sam/test.iso / -r


Extract files/directories from image file.

Example: Extract all files and directories in root direcory of /home/sam/test.iso to /home/sam/test recursively.
Command: poweriso extract /home/sam/test.iso / -od /home/sam/test


Convert image file to other format.

Example: Convert /home/sam/test.daa to standard iso file
Command: poweriso convert /home/sam/test.daa -o /home/sam/test.iso -ot iso


**-r** List or extract recursively.

**-o** Specify output image file name.

**-od** Specify output folder.

**-ot** Specify output image file type. If not specified,
the image type will be determined by file name suffix.

**-volsize** Split output image file to multiple volumes, and set volume
size to . Example: -volsize 100M

**-setpassword** Set password for output image file.

Example: -setpassword 12345678
