  • To most older shells, cd'ing upward through an NFS mount or though a path that contained a symlink as one of the components can (theoretically) be handled in multiple ways, and they usually pick the easiest to implement (i.e. they don't track where you originally came from).

    Personally I prefer zsh to lie to me when I cd into and out of symlink containing paths by making them appear to be "real", though it can be configured to be less transparent. I imagine most modern shells, like bash, handle this as well.
