NFS lockd on server-only machine - bug or feature?

FreeBSD 6.4 lockd does not work when nfsclient is disabled in kernel configuration. It errors out saying "nfslock: no such file or directory".
Shouldn't there be at least a warning in kernel configuration file? :\
It's missing a file or directory on your system. That's the error message. Has nothing to do with your kernel config.
Thanks for response. I do not think you did read my post though.

Missing is device node /dev/nfslock. This node is created if "options NFSCLIENT" is set in kernel conf, and is not created if it's commented out. The error message in /var/log/messages is vague, that's true. It took a little headscratching before I figured out what's wrong.
Looking at the bright side, first time in years FreeBSD lockd is willing to respond to Linux NFS clients. Yea, I know, Linux has those NFS cookies with questionable length. Still, the problem was annoying.
I'd say the line in kernel config should look like this:
options NFSCLIENT # Dude, you need this if you want to use NFS locking
I don't have it in my kernel config either. It gets loaded on the fly when needed.

This is on 7-stable though. It's been a while since I used 6. But since 5 all /dev devices are created on the fly (devfs), not during install or build.
Yes, but that's not the point. I do not need nfsclient, so I built this box without this service/feature. And without any warning lockd refused to run. BTW, I build my boxes as lean as possible and do not build all the unnecessary kernel modules ("MODULES_OVERRIDE" variable in make.conf). So I had to rebuild my kernel to enable nfsclient.
I posted here because I wasn't happy this behaviour is undocumented, probably a bug. But I think it's wrong place for complaining about bugs.

As you see, not too many modules are loaded. ;)
