Solaris support for client nodes
With the new JumpStart Roll, one can now install and configure a Linux-based Rocks frontend to "JumpStart" Solaris-based back-end machines.
Attributes
Can assign "attributes" to nodes at four levels: global, appliance type, OS (e.g., Linux or SunOS), and host. An attribute can be accessed in an XML node as an entity. For example, if you assign the attribute "foo" with the value "123" to compute-0-0 (i.e., with the command, "rocks set host attr foo 123"), then in an XML node file, you can access the value of the attribute foo with "&foo;".
Attributes also enable "conditionals". Using the example above, a "post" section can be optionally executed based on the value of an attribute. For example, if a post section is defined as: <post cond="foo='123'"> then this post section will only be executed if the attribute "foo" is set to "123" for the installing host.
