Net booting is nothing special if your netcard supports it. Trouble with a local cache would be how would you know when the central image changed? Essentially, if you cached a local copy and are not the only one accessing the filesystem, you do not know when the remote file changed.
Normal cache and swap would handle most of the problems you would have. Most used apps would be cached the same as if it had been a local filesystem. Given time and memory starvation, it will cycle out until needed again. I'm sure if you wanted to, your bin dirs could be mounted through a simple fuse fs that would copy them locally when being used. ----- Original Message ----- > Once upon a time SUN had a way to 'net boot' machines, typically > desktops.
