I consider most of daemontools useless software, because it is build
on the wrong assumptions. A normal daemon should not need supervision,
just like a normal daemon can either write its own log files [if the
volume is high] or just use syslog.

runit is a nice program, if you come from SysV world. BSD init is much
simpler, you don't need it for the normal BSD world. Read above for
comments about "supervising programs".

I'm not sure I like the SMF, it has to be carefully evaluted wether
the increase in parallelism really gains noticable speed and wether
it compensates for the more confusion log on startup. Always keep
in mind that higher parallelism can slow down e.g. IO access by
adding seeks.
