It is only an optimization. Any number of syncs are useless for actually syncing the system, since sync(2) only does an async sync (it returns without waiting for most writes to complete). As you pointed out later in this thread, unmount(2) does a sync that works -- a sync sync -- before

Re: svn commit: r222466 - head/sbin/umount

No doubt. :-) If the sync(2) has actual consistency and reliability benefits, it should probably be done by the umount(2) system call, so that other future auto-mounters, etc, also get the same result, rather than having to encode it in every application. If it's done on blind faith,

Re: svn commit: r222466 - head/sbin/umount

If it masks, for example, lateny for a synchronous RPC to the remote mountd to deregister the mountpoint, allowing a cache flush and unmount to take place concurrently, that might be a useful benefit. I'm not sure I see any evidence that is the case in the source code, however. Well, I

If you don't share my preference then it would be good to make new NFS just 'nfs' everywhere (sysctls, fstype, etc.), so that we won't end up with 'newnfs' in random places in five years from now. What you do with old NFS is less important to me:) As you'll see from the post I just sent
