Going down the list:
- inotify - internetz tell me kevents/kqueue is the way to go
- waitid() - issue closed in FreeBSD in February 2013, is it usable?
- epoll, eventfd, signalfd, timerfd - again internetz tell me
kevents/kqueue can do all of this, better yet there is libevent that
can do those portably across linux and bsd
- ptrace - FreeBSD does have ptrace - differences in api/capabilities?
I didn't know about either of these =) looks awesome. Need to look
into how upstart is using those, to see how necessary those are and
how to implement them on FreeBSD.
- netlink proc connector
- netlink udev interface

Apart from FreeBSD folks implementing just recently waitid()?! =))) That's huge.
