by : This is in the 1.0.9 kernel and also in the 1.2.13 kernel. I haven't tried
: any later ones.
: The old Unix trick where you get an invisible temporary file:
: create a new file
: open it
: unlink its name, so it no longer appears in any directories
: write and read as you please, using the file descriptor that
: you got when you opened it
: close it, and it vanishes
: On Linux this works with local disks; but with NFS-mounted directories it
: gives a stale file handle error when you try to write. Removing the unlink
: call makes the error go away.
: Does anyone have a fix for this?
On other Unixes, this is done using a program called 'biod'. An excerpt from
the (SunOS) manual page:

.
When a file that is opened by a client is unlinked (by the
server), a file with a name of the form .nfsXXX (where XXX
is a number) is created by the client. When the open file
is closed, the .nfsXXX file is removed. If the client
crashes before the file can be closed, the .nfsXXX file is
not removed.
FILES
.nfsXXX client machine pointer to an open-but-
unlinked file
I don't think there is a Linux equivalent.
