They're pretty different however. MNFS was for distributed shared memory and was designed to ensure that mmap'ed blocks from the same file remainted consistent across a set of clients. Intermezzo is kind of like "coda done right". The intermezzo name refers to the code that layers between the VFS layer of Linux and ext2/3. OPs from the VFS layer can be redirected to user mode from the intermezzo code. I think intermezzo is doable on freebsd, it just takes time. Also, it is a module. > Maybe they wanted a patent. 8-). Fortunately Peter Braam doesn't worry about patents :-) Peter was here yesterday and tells us that intermezzo can now run over tmpfs. That's cool, I had done something like that two years ago but it was a bit of work and now it just works fine. ron To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
