put stuff like Apache, lightdm/gdm/kdm/sddm, nginx, et al into a
cgroup.
Another option is to push the kernel maintainers to allow delegating
parts of the cgroups tree to other processes, so that the init
system
could say "you get a sub-hierarchy, you get a sub-hierarchy"
without the
complication of multiple separate hierarchies. How do you suggest
this
integration with cgroups be done?
i just want to put services inside cgroups, no socket activation, no
dbus, no dbus activation.
Haha. The problem there is that cgmanager uses dbus! So you need dbus
installed + started before you can use cgroups with later kernels.
i would use it for servers, apache and friends, what i would really
like
is to be able to run multiple instances of the same service each on
it's
own cgroup.
something like
su - user -g cgroup_name -c command or a flag to start-stop-daemon,
cgroups could be created in advance by an init script (a
Required-Start
in lsb slang)
I think cgexec is what you are looking for here. This would break with
later versions of the linux kernel, though, because you need one
centralized writer (e.g. cgmanager or systemd).
