We would like to run a program on several hosts (uVaxen and MIPS) which
would access and write to a common set of files stored on one uVAX but
mounted remotely on the other systems via NFS.
This program was written a long time ago, so advisory file "locking" is
simulated via a create of an empty file, same mechanism as uucp.
Is this a valid mechanism to use under NFS ? Our "research" of various
manual sets evinced only the usual warning re failure of flock, etc. Is
there any "guarantee" that creat() will yield valid results, if attempted
simultaneously from several hosts, accessing a mounted NFS directory tree?
