re: Problem with autounload of nfsserver module

If the nfsserver module has been unloaded, and then you update the /etc/exports files (and HUP mountd), then mountd will call the nfssvc sys-call which will trigger an auto-load of the nfsserver module.

However, the module would only have been unloaded if the previous list of exports was empty; if there were any exports previously, the module would not have been unloaded and therefore would not need re-loading.

i don't see any utility in having nfs server auto unload.

It's no different than any other auto-loaded module, such as compat. If a module is auto-loaded, the system makes a single attempt (after an appropriate timeout) to auto-unload. The module is notified and given an opportunity to prevent the unload.
