The only warning I see is: Warning: extended partition does not start at a cylinder boundary. DOS and Linux will interpret the contents differently. I pretty much don't care how DOS is going to interpret my DASD partitions. > Will it matter that I don't bother to align LUN partitions on "cylinder" > boundaries?

I believe fdisk does things by cylinders by default. I would just use that to create a model setup. > On a related note, what's the lowest 0-relative sector number at which > to start partition 1?

I can't imagine that sfdisk or fdisk would be brain dead enough to allow you to allocate a partition over the area the partition table would have to go.
