https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211361 --- Comment #10 from Dag-Erling Smørgrav <des@FreeBSD.org> --- Nathan, what you're suggesting has a very high probability of breaking scenarios we haven't envisioned and software we're not aware of. This is a matter of *policy*. I want to adopt a *policy* of creating partitions with a specific alignment to avoid potential performance issues. If, at some point down the road, we start seeing disks with, for instance, 8192-byte sectors, our 4096-byte alignment will no longer be optimal, but it won't be any worse than the current 512-byte alignment. The worst-case scenario here is that we waste a small amount of disk space (up to 3584 bytes, less than the total amount of text and code in this ticket, less than 5% of the size of the boot loader, and less than 0.0000005% of the capacity of a typical desktop or laptop harddrive) with absolutely no impact on performance. BTW, gpart and sade are two completely different things; gpart is just a command-line interface to the low-level interface which bsdinstall and sade use to create partitions. -- You are receiving this mail because: You are the assignee for the bug.
