The corosync and pacemaker services are just regular services, and are
configured to start at boot just like any other service in sysvinit. That said, if
you have a two node cluster, starting the services at boot might not be
what you want since you can easily end up with a deathmatch
configuration.

If adding them to runlevels doesn't work, there's a bug of some sort.

There's a basic guide here: http://crmsh.github.io/start-guide/

I'm working on a crmsh version of the official documentation, but it's
not online yet unfortunately.

The crmsh commands simply call
"service corosync start; service pacemaker start"
and
"service pacemaker stop; service corosync stop"

To be honest this has only been tested on SUSE distros by me. I'd be
happy for patches to make this work properly on Debian. :)
