Link atomicity [was Re: NFS Question]

[Jon Hall]

My experience with NFS was mostly with Ultrix/Digital Unix/Tru64.  NFS was
supposed to have the same semantics as a regular Unix filesystem.  My experience
has been that between clients and servers of the aforementioned systems NFS
gave the same dependability that the Unix file systems gave for "shared access
scenarios" to wit:

	When everything is working fine, it works fine.
	When things start breaking, it sometimes breaks.

But NFS V3 of the protocol (Linux currently uses V2 of the protocol) fixes a
lot of that, and I assume that V4 of the protocol will do even better.

As I said..if you really want shared access..use some type of database (and I
use the term very broadly) or network-based lock manager....they are BUILT to
do this stuff.
