What is the best way to compare the OS configuration of two (or more) RHEL 5.X servers? Are there any tools/packages available to do this? Note, I am mostly looking for tunables OS (kernel parameters, etc).
I would like to add the reason why we are looking to do this:
We have a large zLinux footprint and would like to compare our 'standard build' to that of a distro provided by a vendor. zLinux is somewhat a specialized architecture and often has different recommended settings than that of x86_64.
If we have a highly available cluster of servers, to compare/ensure that the OS configurations are consistent between them.
Note: I'm not looking for a centralized solution like puppet or chef. I agree these are the optimal solutions are definitely on the roadmap, but not what I'm looking for right now :)
