The ZFS or UFS file system is hierarchical, starting with the root directory (/) and continuing downwards through a number of directories. The Oracle Solaris installation process enables you to install a default set of directories and uses a set of conventions to group similar types of files together.
For a brief overview of Oracle Solaris file systems and directories, see filesystem(5).
The following table provides a summary of the default Oracle Solaris file systems.

The root (/) and /usr file systems are required to run a system. Some of the most basic commands in the /usr file system (like mount) are also included in the root (/) file system. As such, they are available when the system boots or is in single-user mode, and /usr is not mounted.
