Yeah, that's actually something I've long wondered about implementing; shouldn't be too hard, really. Never found the tuits, though :) For those who don't know what the idea is: /usr/bin/ftp is a symlink to /etc/alternatives/ftp, which in its turn is a symlink to /usr/bin/tnftp. The /etc/alternatives/ links are maintained by the update-alternatives utility which knows about priorities, defaults, slave symlinks (e.g. if the ftp(1) utility's symlink changes, it would be best to also change the ftp.1.gz manpage symlink, wouldn't it?), and a whole lot more. =46rom a user's standpoint, all you have to do is install a package that declares a higher-priority alternative, and update-alternatives switches the symlink behind the scenes (unless you have explicitly specified one of the choices). If you don't like that, run update-alternatives by hand, and your choice is honored even if later a package with an even higher priority is installed.
