I would expect NFS store to work in environments that support file
locking over NFS. For example, NFS flock(2) does not work with Linux
kernels up to v2.6.11. For the list of environment-specific file locking
system calls used by the certificate generator, see Ssl::Lock::lock().

The generated certificate database is just an optimization/cache.
Logging certificate cache operations would probably be as useful/useless
as store.log is for the HTTP cache. It would be good to discuss and
target some specific use cases before designing where and how to log
certificate operations.
