For these media, -msinfo alone would not be enough to perform appending of an
ISO filesystem. The filesystem driver will need a hint to find the start of the
most recent session. For example put an ISO filesystem at address 1 GB:
mkisofs -C 0,524288 ... | \
cdrskin dev=/dev/sr0 -v fs=32m -eject speed=4 write_start_address=524288s -
The superuser may then do:
mount -t iso9660 -o ro,sbsector=524288 /dev/sr0 /mnt
Note: On my linux-2.4.21-215 mount works only with sbsector <= 337920 (660 MiB)
To extend a filesystem already existing at address 0
mkisofs -C 0,524288 -M /dev/sr0 ... | cdrskin dev=/dev/sr0 ...
Record the number 524288 for usage as first number with -C at the next
