this may be good enough for many cases, but it'll be wrong in the case of processes that are rapidly forking. I'm not sure what your exact use case is, but in general cgroups are the best way to keep track of processes. once the moment-in-time info is snapshotted for userspace (eg. pstree) to use it's already out of date, wheras things like cgroup freeze/thaw and kills are definitive if used properly. ie. no rogue processes are possible. cheers, robin _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
