The SunOS equivalent of this is 'tmpfs'.  However, I'm warned by a fellow I 
know who programs UNIX kernels for a living, that it's terribly buggy, and 
will probably crash.  Various SunOS updates, i.e. 4.1.1 and 4.1.2 (read 
Solaris 1.1 and 1.2) have apparently fixed these bugs, but enough remain
to cause problems.  The OSF/1 implimentation of the memory file system is
much more solid.

from the man page...

NAME
     tmpfs - memory based filesystem

CONFIG
     options TMPFS

SYNOPSIS
     #include <sys/mount.h>
     mount ("tmpfs", dir, M_NEWTYPE|flags, args);

DESCRIPTION
     tmpfs  is  a  memory  based  filesystem  which  uses  kernel
     resources  relating  to  the  VM  system and page cache as a
     filesystem.  Once mounted, a tmpfs filesystem provides stan-
     dard  file  operations  and  semantics.   tmpfs  is so named
     because files  and  directories  are  not  preserved  across
     reboot or unmounts, all files residing on a tmpfs filesystem
     that is unmounted will be lost.
