It was changed from 63 in 2010. > Is it worth while updating the defaults so that OpenBSD partition > layout will be optimal for SSD or other Virtualized RAID environments > with 1MB Chunks, What are you trying to optimize with this? FFS2 file systems reserve 64 kB at the start of a partition, and after that it's filesystem blocks, which are 16/32/64 kB, depending on the size of the filesystem. I can barely see an argument for aligning large partitions at 128 sectors, but what purpose would larger multiples serve? > Is there a down side to moving the default offset to 2048 ? Not really. It wastes a bit of space, but that is rather insignificant for today's disk sizes. -- Christian "naddy" Weisgerber na...@mips.inka.de
