Yes, I do this too. $HOME is managed by automount. So I don't even need to preallocate the filesystem. In addition, I have a /tmp2 subdirectory. It is like $HOME in that it is managed by automount. In /etc/profile, I make $TMP, $TEMP, $TMPDIR, et al., all have a value of /tmp2/$LOGNAME and mark them READONLY. Most UNIX utilities use one of these environment variables for allocating "temporary" files. And so every user ends up with a unique temporary file space as well a as unique HOME. This doesn't stop people from using /tmp and I don't try. But I do tell them how to get temporary space that is not going to be exhaused by someone else.
