We're just starting to use Eclipse 3.5.1 p2 for product deployment and
updating. Our linux applications are installed using Scenario #3 - shared
configurations.

Our users are seeing stale NFS file exceptions when we update our product
using the p2 director from the command.

It appears that p2 does not support multi-user installs since the shared
configuration filenames change! Am I doing something wrong?

Found my own fix. The problem was with the registry cache changing. The
startup script for the shared product no includes the Eclipse command line
flag -noRegistryCache.
