Sure. But you weren't expecting to share an agent between separate ssh logins, were you? Defining a per-machine "session" gets terribly hackish, as the Gentoo keychain program shows. You get into this whole mess of trying to get some way of communicating data between independent logins, which gets a lot more difficult than "stuff it in ~/.foo" with fun things like NFS /home in the mix. /tmp is problematic since you can't use well-known filenames. You basically end up having to trawl /tmp looking for an active socket or something, or try ~/.foo/$hostname/bar, and $hostname has its own problems... -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/fedora-devel-list
