Using sudo with relocatable hostnames

This solution works great if you want to grant equal access to both boxes.  However, what we are doing is fairly typical in that the failover server runs a full size development instance that has many more people allowed access to it than to the production instance.  

Can we come up with a solution that will allow differing access for differing User_Alias groups?

Why don't you set up your package or cluster name up as a host_alias?

Host_Alias	PACKAGE_A=SG_Node1, SG_Node2	# Package only runs on nodes
1 and 2 only.
Host_Alias	CLUSTER_NAME=Package_A, Package_B

I appreciate the feedback.  However, with over 100 HP boxes, we are having
to be fairly committed to developing a consistent sudoers file that will be
comprehensive for the environment.  Then, as a change is made, the file will
be copied out across the environment.

Anyone have any other suggestions on how this might be accomplished?

You can just use ALL for the hostname.  That's what
I did when I managed hp-ux clusters.

Doesn't hurt, as long as you don't blindly copy sudoers
files to other machines.
