 there is no difference between -sao and -tao. If ever, then -tao will be the
 mode which preserves the current behavior.
 
-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 ...

-  mkisofs -C 524288,1000000 ... | cdrskin write_start_address=1000000s ...
