Jail is part of the o.s. and yes the configuration management utility
should be able to generate usable jails. 

 let me see if i can describe where i'd like to take this.

One of the things that all of the BSD's and linux for that matter is
missing is a way to handle multiple system configs. Say you have 50
DragonFly boxes you have to manage the configs on .. quite simply it
gets to be a pain in the ass.. so rather than write a once only throw
it away after we have this thing working tool. I propose we write 
somthing usefull outside of the sysinstall realm. Somthing that can 
be used by sysinstall. This has to be intergrated into the package 
system. What i'm thinking is a client/server model with the packaging 
system using xml to tell us how to configure that package. 

lets say a package needs to know what interfaces to bind to.
 it can tell us that it needs a drop down list box of interfaces to
select from. Or whatever user input it needs. what i'm trying to
communicate is that the package will actually drive the user interface
with the cm system just displaying information, and collecting information.
done this way you could create modules for say controlling cisco devices.
just as easily as you could setting up BIND.

to replay an install, you could just replay the xml data, sent to the 
packages back. fully customized install scripts would be very easy to 
create. Packages could be built for ports that integrate fully with 
the cm utility. so for once and for all managing a huge number of
opensource boxes wouldn't be a complete nightmare.
