I know what a symlink is, but what is a "slave symlink"? I upgraded today (potato using apt-get) and I got this:
warning: /usr/bin/wish8.0 is supposed to be a slave symlink to /etc/alternatives/wish8.0, or nonexistent; however, readlink failed: Inva gument Leaving wish8.0 (/usr/bin/wish8.0) pointing to /usr/bin/wishstep8.0. thanks -- Andrew
