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.
|Cache File System||CACHEFS||Local caching for remote file systems|
|File Descriptors File System||FDFS||Opening file using file descriptors with explicit names|
|First-In First-Out File System||FIFOFS||Accessing data (named pipes)|
