I think, upstart should still be operational. Inotify is (mostly) used for monitoring the directory with the Upstart configuration/job files. If nih/watch.c was a dummy on kfreebsd, one would propbaly have to tell upstart explicitly about new job configuration, e.g. by telinit Q. I'll let Scott answer that more properly though. > * some "#ifdef __linux__" around "#include <linux/ptrace.h>" I think this is the most hairy part. ptrace is used for tracking the pid of forking/daemonizing processes, and as such a central part of upstarts functionality. So it needs a proper port to a similar mechanism on kfreebsd. As a further note, Scott intends to replace the ptrace code with a netlink connector approach in the next major upstream release, which is supposedly 0.10. Again, Scott should be able to tell you more. Cheers, Michael -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth?
