[Wine] Multiple instances of wine on different machines with $HOME on NFS

[Steffen Neumann]

Hi,

we're running wine on a number of Linux machines
which get their $HOME via a NFS server.

In particular, we have a windows commandline program 
(a data format converter for mass spectrometers, not that it matters) 
things work fine as long as I am running only one instance of wine.

If I have several wine instances on different boxes 
running in parallel, they seem to corrupt the registry.

I have not found anyone with a similar problem, let alone a fix.
I might have to copy a temporary .wine into /tmp 
and use $WINEPREFIX in a per-machine specific manner.

Or is there some easier way ? 

Yours,
Steffen

P.S.: 
I'll append the following snippet to
http://wiki.winehq.org/HomeDirectoryOnNFS
once it is operational again:

Apart from performance problems, you might encounter problems
with .NET2.0 if your C: drive lives on a network,
e.g. a "NFS System.IO.FileLoadException: Failed to
grant minimum permission requests." failure.

The reason is that .NET2.0 by default considers everything coming from
the network as possibly tainted. Usually you can issue something like
"CasPol.exe -m -ag 1.2 -url file://... FullTrust" command 
to make e.g. your intranet trusted.

Unfortunately CasPol.exe is living on C:, and is not trusted 
if that is served via NFS ... If you still want C: to be on NFS 
(despite the above mentioned performance penalty),
the fix is to copy your CasPol.exe to a local directory, and use 
wine /tmp/CasPol.exe -m -ag 1.2 -url "file:///c:\\*" FullTrust
