Patch Management over mixed unix platforms

Does anyone know of any tools that manage the rollout of patches across multiple types of Unix platform ( eg Solaris, Aix etc ).

I am looking for something that does a similiar job to SMS or WSUS in the Windows world

Well, there is this:

http://rsug.itd.umich.edu/software/radmind/

I do not use it (yet?) but quite a few others do.

you can maybe try using tivoli, although i hear it is painful...it has not work really great for me.

you can also try a product called "on Stage". you can push all sort of patches and packages through it via a respository type of setup. It works really well for linux implementations, i think it can work for all sorts of OS depending on the agent installed.

cfengine.org might also be a solution.
