Don,
The main reason is, we don't want to waste device numbers in order to keep
the
number of supported devices high. Linux in General can access a maximum of
64k
block devices (partitions). If we would (like Intel) allocate 16 device
numbers
per volume in order to allow for 15 partitions per volume, we would
restrict Linux
to 4k volumes per system (assumed, that you don't have any other block
device!)
Best Regards
Holger Smolinski

FDASD only allows 3 partitions on a compatibility disk. However, in every
case I have looked at there is room in the vtoc for more partitions. Does
anyone know if there is some reason for not allowing more partitions on a
cdl disk?
Thanks,
Don
