It really doesn't have any business being a bootstrap tool. However, for reproducible build output, FreeBSD added dd status=none because it was otherwise difficult to suppress the status information, but retain any errors that might happen. There's no real reason that dd has to be a build tool, other than we use status=none unconditional. Remove dd from a bootstrap tool entirely by only using status=none when available. This may also help efforts to build the system on non-FreeBSD hosts as well. r316109: Don't hardcode input files for stage 1/2 bootloaders; use .ALLSRC instead This is a better pattern to follow when creating the bootloaders and doing the relevant space checks to make sure that the sizes aren't exceeded (and thus, copy-pasting is a bit less error prone). r316132: Parameterize out 7680 (15 * 512) as BOOT2SIZE, similar to sys/boot/i386/zfsboot/... This is being done to make it easier to change in the future--this action might be needed sooner rather than later because of gcc 6.3.0 bailing, stating that there is negative free space left (deficit) in the boot2 bootloader.
