Up Linux Advantages Install different directories on different hard disks. Can have some mounted via NFS to have a common set of programs, this keeps all machines at same version number automatically . Easily clone systems. System can be installed remotely. System is actually installed from the media without having to copy the files a couple of times.
Disadvantages Only install in a single directory.
Major problems with different versions. Extremely difficult to realize a system with shared system directories. 1 Cloning is very cumbersome. Cannot simply copy the systems as the Security ID is duplicated. Must add all users on one system or the other.
