Solaris Pseudo-File Systems

Solaris supports several types of memory-based file systems. These are referred to as pseudo-file systems. Because they are memory-based, these file systems provide faster access to the data stored in them. However, they are not permanent. In addition, any directories or files in pseudo-file systems are lost when the file system is unmounted or the system is rebooted/shut down. Table 6.5 describes the pseudo-file systems supported by Solaris 9.
