Pseudo File Systems

The TFS pseudo file system is not included in the SunOS release 5.7 software.

Following are the pseudo file system systems that are included:

• CACHEFS--used to improve performance of slow devices such as CD-ROM.

• PROCFS--memory resident file system that contains a list of active processes, by process number, in the /proc directory. See the proc(4) man page.

• FDFS--lists explicit names for opening files using file descriptors.

• FIFOFS--contains pipe files that give processes common access to data.

• NAMEFS--used mostly by STREAMS for dynamic mounts of file descriptors on top of files.

• SWAPFS--provides default swap device when the system boots or you create additional swap space.
