SubjectRe: Solved - How to change the FSINFO for nfsd?
Quoting "J. Bruce Fields":

Just in case someone needs to know this information. Please note that
I am not a
programmer. I am just hacking away.

Most of the credit for the hack goes to the person in the forum
mentioned below
for finding the Mac NFS behavior.

The changes done seem to work well.

I am dissapointed that Apple made changes to NFS to a point that we
have to use an Apple NFS. I thought that NFS is open. Anyway with
these changes, a Linux server can be used.

Anyway this problem only happens from with in the video editing application,
Final Cut Pro, an Apple product. I hope someday a good video editing
application
comes to Linux. I am willing to pay for Linux video editing
application. It must
be good that is.

Anyway here is the patch done.
