Re: Patching Solaris machines with cfengine

I agree with K that you shouldn't just go winging patches on machines, 
however we use cfengine, along with a list of patches that should be applied 
and the CheckPatches, GetApplyPatch scripts that you can get from Sun to 
automate the whole process.

We haven't run into any problems yet (cross my fingers, etc).  We tend not to 
worry about the fact that you should be rebooting machines after kernel 
patches etc.  All of our environments are development only and we take that 
risk knowingly.  I guess we'd rather patch the machines then not patch at all.

Production is a whole different ball game.

If you want more info just say so and I can share the cfservd configuration, 
one line shellcommands that we use for this.

cheers
