Let's clarify somethings. /home and /usr home will always be two different entries in your root directory. /home could be a symlink to /usr/home, it could be a subdirectory of /, or it could be a mountpoint for another filesystem. /home is never under /usr. /home is /home. That said, /home could be a symlink pointing to /usr/home. Whether that is true is simply up to you and how you want to set up your system. You have all of the same options for /usr/home. /usr/home can be a symlink, a subdir of /usr, or you could just as easily mount a filesystem there. That all said, one typically symlinks /home to /usr/home or vice-versa. Which you chose is pretty much an asthetic choice. No reason /home and /usr/home can't be completely different directories, however. But why would you want to do that? > Let's say /home is getting full, and I write something > into it.

Stuff will be written to whatever filesystem you write it to. The situation in never ambigious and no dynamic usage is done by the system. Trying to interpret what you said earlier, you want to have /home be a mount point at have /usr/home be a symlink pointing back to /home, right? In this case, anything written above /home or /usr/home (since /usr/home == /home) gets written to that filesystem mounted at /home. Always. -- Crist J.
