Right. And if we suspect that the APIs will always be at least subtly different, then keeping them obviously visually different seems to have some benefit. (i.e. systemctl set-property httpd.service CPUShares=500 MemoryLimit=500M vs dbus-send cgmanager set-value http.server "cpushares:500 memorylimit:500M swaplimit:1G" ) rather than have admins try to remember "now why did that not work here, oh yeah, MemoryLimit over here should be Memorylimit" or whatever. Then again if lmctfy is the layer which admins will use, then it doesn't matter as much. > It would be best if we could get a common DBUS api specc'ed and all > agree to it. Serge, do you feel up to that? Not sure what you mean - I'll certainly send the API to these lists as the code is developed, and will accept all feedback that I get. My only requirements are that the requirements I've listed in the document be feasible, and be feasible back to, say, 3.2 kernels. So that is why we must send an scm-cred for the pid to move into a cgroup. (With 3.12 we may have alterntives, accepting a vpid as a simple dbus message and setns()ing into the requestor's pidns to echo the pid into the cgroup.tasks file.) -serge ------------------------------------------------------------------------------ Rapidly troubleshoot problems before they affect your business.
