> the idea to start services concurrently during boot isn't new and the > question why FreeBSD doesn't do it has popped up on the forum and > mailing list occasionally. So, why not give it a shot? As someone who uses FreeBSD on hist laptop and is constantly annoyed by the lack of suspend-to-disk, every second trimmed of from boot time is a win. In line of the recent FreeBSD problems & solutions discussion, would any commiter take time to review and commit this? "FreeBSD 9.1 introduces concurrent startup, improves boot speed" is the kind of buzz we're after. > Any ideas and feedback are very welcome! One thing to try is to attach a diagnostics feature that will produce data about rc script dependencies and execution times, which can be used to visualize which scripts take most time, and how to reorganize dependencies to improve boot time (one example I noticed is moused: it is only started after network is up, which is a shame, since it could easily start while DHCP negotiation is in progress).
