I usually just mount the iso image and treat it as a read-only file system. But as long as it works for you... . The first thing I do after mounting it is verify the checksums in situ in the image.

You can use the --quiet option (--q for short) to have the program spit out only problematic results. -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/
