I guess people got used to describing public key operations in terms of RSA (keys and methods, I guess). But for reasons I can't remember, I specify -tdsa when I run ssh-keygen, so I get DSA keys not RSA keys.
RSA was patented for a long time and unavailable to normal folks. So DSA was used. But a few years ago the RSA patent expires and now we can all enjoy RSA goodness.
And the sshd_config term applicable to ssh2 seems to be PubKeyAuthentication, so it looks to me we might be speaking more generically if we said pubkey (publickey, or public key) instead of RSA (or DSA).
Yep. There are various different pubkey schemes and RSA and DSA are two of them.
