The each logical partition is defined by extended partition table (EBR) http://en.wikipedia.org/wiki/Extended_boot_record EBR contains usually two partitions: 1/ data partition (used as a logical partition) 2/ extended partition (used as a pointer to the next EBR) so if you have 5 logical partitions then there is usually 5 small partition tables and 5 extended partitions :-) The partitions are usually NESTED. The top-level (outermost) extended partition is the partition visible for end-users in fdisk output. > If "contained in the surrounding partitions" > means "contained in the containing partitions", it says nothing.

NESTED: every extended partition is contained within a parental extended partition. IMHO nothing other is usable in Linux. > > > CHAINED: every data partition is contained in the surrounding partitions > > and disjoint from all others, but extended partitions may lie outside > > Is a data partition the same as a logical partition? Yes. IMHO the comment is mess as well as the implementation :-) Don't think about it too much. We need to rewrite sfdisk and cfdisk.... > > scriptreplay [options] [-t] timingfile [typescript [divisor]] Fixed in the usage().
