Ah, but this is exactly the problem to watch out for. Linux especially.

Linux NFS support is generally around v2. Some of the distributions out
there have been putting the v3 support in, but the stock kernel is not there
yet.

I discovered this issue when a mod_dav users was trying to store their lock
database across an NFS mount. I used flock/fcntrl and it failed, and
somebody on the mod_dav list explained the issue.

We may be able to devise a test that people could run if they plan to set up
an NFS-based SVN system. The test could say "yes, the locks work properly,
so this is safe" or "this NFS setup is not functioning well enough to run
SVN across it."

*shrug*

It is a little ways off :-)
