That might have been a "traditional" reason for a shared /usr. However, the package manager can't cope with this setup since you have some components of a package installed locally and some remotely for all systems using the "shared" part. It's an impossible situation to actually cater for in real life. Has anyone ever actually *done* this? Just having /usr on NFS doesn't make it shared if it's only used by a single system, or unless you have a cluster using a common image, but even then it's not shared between systems since they are just clones of the same system--you wouldn't run dpkg on them. As an aid to the maintainability and security of a system, it's nice to be able to mount /usr readonly and also to run without it using a minimal /usr for recovery and troubleshooting purposes. Looking at GNU/Hurd, /usr is a symlink to /. If we were to make /usr non-separable, maybe this would be the way to go. Regards, Roger -- .''`.
