Or maybe not C:/usr/X11R6, but /dev/sdd1.

Extending this through NFS (or any other remote file system, for that matter) is usually a rather bad idea because you can get deadlocks pretty damn quick if you're not careful, but I'd like to have the option.
I have one really basic requirement for my NFS daemon -- I need to be able to rearrange local disks on my server machines, and NO client should require any change. I also need to be able to reinstall a machine by mounting master:/ onto /master, /dev/sda1 onto /slave, mount the required local file systems to /slave/usr or /slave/boot or whatever, cp -av /master/* /slave, lilo -r /slave, umount -a, reboot. Done, except for a few trivial changes under /slave/etc of course, like for instance the IP address. ;-) If this installation procedure would require me to mount /master/usr and /master/var and /master/boot and /master/usr/local and /master/usr/X11R6 and /master/you/forgot/one, I'd go crazy, and it'd be faster+cheaper to burn an image of master:/ onto CD-ROM every week.
This is exactly how the usermode NFS daemon works. This is how I want the kernel NFS daemon to work too.
I do know that no other kernel-based NFS server does this. So what?
