This is reliable, but not very efficient. It requires at least 2N file
checksum calculations (where N is the number of files in the tree
being copied or verified) on every pass. You are also using 2N space,
since you are storing a copy in ${sys.workdir} to compare against.
Another suggestion: use your operating system's package manager to
package Nagios, and then use Cfengine to install the package. That
would also probably result in an end system that is not as confusing
for an admin that is not familiar with Cfengine.
I think more community examples would go a long way to helping the
initial learning curve. We are working on that, so stay tuned.
