Appendix A # Installation Directory Structure The directories that contain the Foundation Services are created on the master-eligible nodes. Most of the Foundation Services software is installed in the `/opt/SUNWcgha` and `/etc/opt/SUNWcgha` directories. However, device drivers in the Foundation Services software are installed in standard Solaris directories, for example, the `/kernel/drv` directory. The following table summarizes the installation directory structure. Table A-1 Installation Directory Structure
Directory | Description
--- | ---
`/etc` | Files that have read and write permissions, and that are specific to a given node. The `/etc/opt/SUNWcgha` directory is used for configuration files. The `/etc/opt/SUNWcgha/init.d` directory is used for startup scripts.
`/export` | Optional. Subdirectories are created by the `nhinstall` tool during the configuration of diskless nodes. If you install manually, you create the subdirectories for the diskless nodes.
`/opt/SUNWcgha` | Read-only files. These files are not shared.
`/opt/SUNWcgha/lib/locale`$NLS_LANG`/LC_MESSAGES` | Message catalog files.
`/SUNWcgha/data` | Shared DHCP configuration data.
`/SUNWcgha/local/export` | The mount point for exported data and executables.
`/SUNWcgha/remote/lib/locale/`$NLS_LANG`/LC_MESSAGES/` | Message catalogs shared across multiple diskless nodes, for example, from middleware applications.
`/SUNWcgha/services` | Packages shared by the master-eligible nodes.
`/SUNWcgha/swdb` | Shared package repository.
`/var/opt/SUNWcgha` | Standard log files.
`/var/run/SUNWcgha` | Temporary files that are deleted when the node reboots.
`/var/tmp` | Temporary files that are not deleted when the node reboots.
