Why the change on the user interface > (of kernel building)? It isn't "gratuitous" at all. The bus settle delay affects more than just booting, it also affects how long we freeze the SIM queue after a bus reset and how long we freeze a device queue after a BDR. Some folks may have devices that don't need really long bus settle delay, and may not want their machines hung for a second after a BDR or bus reset. We could have changed the option name, which would be an interface change. Kernel building "interfaces", if you can call them that, change all the time. We've already changed a number of them in the CAM switchover. > People thing easily in seconds. Not so well in milliseconds.

(it's not too late to change back... :)) I don't think it'll turn out to be a big problem, really. If folks can't figure out how many milliseconds are in a second, I question what they're doing using a computer in the first place, much less FreeBSD. :) If enough people are really upset about this, we can make it something like CAM_BUS_SETTLE_DELAY instead.
