Great idea. I liked it so much I bought the company -- er, I mean, I wrote something like this. It's private name spaces for Linux and FreeBSD (among others) and it allows you to mount things from remote file servers into your name space. There's a technical paper at www.acl.lanl.gov/~rminnich that is a brief overview. I'll get longer technical papers and such out there this week I hope. Writing servers is pretty easy, I have two reference implementations. In fact one server is a .c file plus a server library, so the actual server is quite small. Remaining task is to get a VFS for FreeBSD. The v9fs is a start but I need help getting the rest done. It's pretty easy to do though -- I was amazed at how quickly the Linux version went once I had a v9fs-like VFS for Linux. If interested let me know. ron To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
