Do you have some suggestion about > this? Not really. As I've said, I can easily change that colon to something that works. And, if you take my suggestion, SSH_AUTH_SOCK would work as before. So it would only be necessary to change anything if I were to start using SSH_AUTH_SOCK_FALLBACKS. > Or as it is a new env var we can just warn the users and then they > will have enough time for changing their scripts (like in your case)? I think if its a new environment variable, nobody will use it in old scripts, so there is no cause for a warning in advance. But I'm not sure what actual openssh developers have to say about this (I'm just reading the mailing list...).
