On your UNIX filesystem, you will build a disk file named something ending in ".iso" which is an exact image of the CD-ROM that you will be recording. This mastering process is done using mkisofs.
mkisofs-a # Include all files -f # Follow symlinks, don't write 'em -J # Enable Jolet -o /var/tmp/disk.iso -r # Rational Rock Ridge. uid=0 -T # TRANS.TBL for DOS -v # yack yack yack -V VOLID # Volume Id pathlist...
NOTE: If you use -f, and have the directory full of symlinks to directories, and you use "*" as the pathlist rather than ".", the top level of structure will be totally flattened away.
NOTE: Mike has a pre-packaged shell script which does this for you, in ~mike/bin/mkcd.sh
To record a ".iso" CD-ROM image onto a SCSI CD-ROM recorder, use these steps. These examples assume that your CD-ROM recorder has SCSI ID 4, and that your ".iso" image is called /var/tmp/disk.iso
First, Load a blank recordable CD-ROM (CD-R) into the recorder, and test to make sure that you have good communication across the SCSI bus with the recorder. Run:
cdrecord -inq dev=0,4,0
Second, make a "dummy" recording (laser off), to test transfer rates and file permissions. You may abort (^C) this after 10-20 Mbytes.
cdrecord -dummy -v speed=4 dev=0,4,0 /var/tmp/disk.iso
Third, record for real by removing the "-dummy" option, e.g.:
cdrecord -v speed=4 dev=0,4,0 /var/tmp/disk.iso
Mount the ".iso" image as if it were a CD-ROM.
mount -r -t cd9660 -o loop /n/fs/var/tmp/disk.iso /mnt
mount -r -t cd9660 /dev/cd0c /mnt
