This is not necessary. One can setup everything needed in ~/.ssh/config on a per host basis, i.e. key or user to connect with. Since the plugin always runs as root, you might leave out '-l root' as well. > So in this form this plugin can be configured as a clone or as a set > of resources and location constraints. > > > I'd be very pleased if this plugin gets its way into Linux-HA distribution. > Sure. Could you please just drop the ssh_command parameter. Many thanks for the contribution.
