17 Note that you, portage and root are 3 different users, so you must make
18 key pairs for reach on each source machine you will ssh from.
20 Then you need to add each of those user's public keys to each
21 destination user's authorized_keys file on each machine you want to ssh to.
23 That can be a lot of key copying :-) 3 x 3 x # of machines
25 Finally, on each machine you will ssh from and as each user who will do
26 the ssh'ing, you must run keychain at least once to store the key creds.
27 They should then persist until reboot, when you must run keychain again
28 for each user.
30 The idea is that a given user's keychain creds are valid over all that
31 user's login sessions on a machine. User's cannot share each other's
32 keychain
