In the Solaris world, processes are placed into cgroups (projects) by
one of two mechanisms:
1) inheritance, with everything I create in my existing project.
To get this started, there is a mechanism under login/getty/whatever
reading the /etc/projects file and, for example, tossing user davecb
into a "user.davecb" project.
2) explicit placement with newtask, which starts a program or moves
a process into a project/cgroup
I have a "bg" project which I use for limiting resource consumption of
background jobs, and a background command which either starts or moves
jobs, thusly:
case "$1" in
[0-9]*) # It's a pid
newtask -p bg -c $1
;;
*) # It's a command-line
newtask -p bg "$@" &
;;
esac
A rules engine would be more useful for managing workloads once
they're assigned, as IBM does on the mainframe with WLM and goal-directed
resource management. (They're brilliant in this area, by the way, so
I'd be inclined to steal ideas from them (;-))
