After looking into the upstart, a few questions: 1) /etc/init.d/ceph and /etc/rc2.d/S20ceph still exist after installed the ceph, , does this will conflict with the upstart? For the /etc/init/rc.conf also in the /etc/init/. 2) how can I stop all daemons on different nodes in a single cluster? On centos, we can use "/etc/init.d/ceph -a stop" to stopping remote daemons 3) what to do if I want to use sysvinit only on Ubuntu ? just move the files /etc/init/ceph*?
