Ok. I came to my conclussion as you said that haing both Daemons and Tasks  
can be confusing, and that we latelly have focused on Tasks. That, along  
with not having something to monitor daemons, made me come tho the  
(perhaps rash) conclussion that daemons were obsolete.

Ok. But I still think that that are our primary goal and future features  
should just be in the future.

Yes, I know. I'm aware of that there exists such prepared skeleton for  
having a monitor daemon included, but afaik there are no recipe or package  
for (any resent version of) runit or similar, so in reallity noone could  
use it without some work.
