The Loopback File System

The Loopback File System (LOFS) lets you create a new virtual file system so you can access files by using an alternative path name. For example, you can create a loopback mount of root / onto /tmp/newroot. The entire file system hierarchy looks like it is duplicated under /tmp/newroot, including any file systems mounted from NFS servers. All files are accessible either with a path name starting from /, or with a path name starting from /tmp/newroot.

See Chapter 27, Creating File Systems (Tasks) for information on how to create LOFS file systems.
