On a related but unrelated subject... I had some problems with NFS. The
symptom was that ld was creating bad file and known good source code
did not work. After some time, this is the responce I got from Apple.
You asked about the problem where the loader can write a block of
zeroes to your output file when you are linking across NFS.
Apparently, the problem is caused by race conditions between
the multiple processes you get to do the file I/O. We are currently
looking at a fix for this. A short term solution would be to run
without biod daemons, which are the asynchronous block I/O daemons.
Without these, you will get serial I/O, thus eliminating the race
condition.
And sure enough, that took care of my problems.
