I'd prefer to leave it off. It means one less file to assure myself is safe, if I were thinking with my paranoid security hat on. Most configurations don't need it, and those that do have to edit /etc/ssh/sshd_config on the server side anyway. A comment there will be the most effective way to getting to it. /etc/ssh/sshd_config has already: IgnoreRhosts yes # Uncomment if you don't trust ~/.ssh/known_hosts for RhostsRSAAuthentication RhostsRSAAuthentication no The make.conf variable would be useful not to whack that suid bit off next time you buildworld.
