Mount Points for Shared Directories

Sun Update Connection – Enterprise manages software, so efficient sharing in an Sun Update Connection – Enterprise system concentrates on software-relevant directories. Sun Update Connection – Enterprise shared resources support is relevant to Linux operating system directories, not user-defined directories.

The most important shared directories are /usr and /opt.

The /usr directory contains system libraries, administrative commands and files, and the main files for installed applications. When you install an application, its main parts go in the /usr directory. Other directories hold the configuration files and data, the type of things that you want to sometimes change. Sharing the /usr directory means that multiple VM users (master host and sharing hosts) can use the same applications, although the largest part of the package is be installed only once (on the master host).

The directories that you want to share must be mounted in /proc/mounts of both the master host and the sharing hosts.
