This HOWTO is to guide the creation of a Yellow Dog Linux Install DVD using either x86 or PowerPC Linux.
After downloading your image into your Linux box, do this:
growisofs -dry-run -Z /dev/cdrom=sample.iso
... in order to perform a test run. Remove the -dry-run flag to do it for real. the 'Z is equivalent to the "dev=" flag in cdrecord, telling growisofs where to find the device and ISO.
