I really really wanted to make this land for infernalis, but it'll have to happen quickly if that's to happen. My suggestion (before I got sick) was to merge all of the systemd related changes into a wip-systemd branch and test/fix the integrated pile. I'd start by just grabbing a few downburst VMs, instaling simple clusters with ceph-deploy, and geting used to the user experience of starting/stopping daemons, making sure things behave on boot, updating some of the docs, and so forth. I suspect there are some minor ceph-deploy changes need to systemtl enable the mon and mds daemons (osds would start indirectly via udev). ...but I would *love* it if infernalis used systemd natively for fc22 (which has a gitbuilder now) and rhel/centos7. I'm not sure what is downstream for ubuntu, but that could be pulled in as well. We aren't building upstream suse packages so nothing to do there at this point except merge whatever Owen sends us :) sage -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
