What you call a "filesystem" is really a name-resolution facility which translates what you think of as a "filename" into a particular kernel object. That kernel object can be a file on a persistent media, a file on a non-persistent media, a socket, a FIFO, a device, a process and almost any oddball thing you can can come up with. Persistence is a very optional property and it has nothing to do with the object living in the filesystem naming space. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
