If you want to add a user to all of the components in bugzilla, you don’t have to go through the gui. In fact, you can change just about anything in bugzilla by connecting to the database directly and modifying the tables.

Connect to the database, match up user id’s to user names, figure out which components you want to modify, then update the component_cc table. Step-by-step.

ls -lh dsl-4.4.10.iso

-rw-r–r– 1 ninja ninja 50M 2009-08-28 13:11 dsl-4.4.10.iso

Mount the original iso image you want to modify
mount -t iso9660 dsl-4.4.10.iso /mnt/original -o loop
Copy the everything that you just mounted to another …
