Q: you say systemd requires CONFIG_CGROUPS=y. Why is that? It's taking over sysvinits job afaiui, what does that have to do with cgroups?I think they were using it to track all the children forked by a service and cleanup all of them if need be. So they just need it for logical grouping functionality and don't require any controllers as such.Hm. Controllers are perhaps not required, but cpu controller was configured and used without consent. I didn't receive an offer.
Just set DefaultControllers= in /etc/systemd/system.conf to an empty string and systemd will not make use of any hierarchy beyond its private name=systemd named hierarchy. Lennart -- Lennart Poettering - Red Hat, Inc.
