Indeed. Unfortunately, I am still stuck with the perf/regression testing, and still have to write a CBA report for the directors. The other option is to wait for our vendor (RHEL or OEL) to adopt the new FS as a default/recommended option and implement it during the next cycle. To give you an example of what enterprise admins are up against, it took me almost 4 years and over 2 million dollars to migrate end-to-end from 1024 to 2048bit SSL.
