Subject: sshroot: better handling of getting keys
X-Git-Url: https://www.dehnerts.com/gitweb/?p=user%2Falex%2Fsoftware%2Fmy-snippets.git;a=commitdiff_plain;h=5ec775cdf19bf05c4948af3045fbf7abf17679f2

sshroot: better handling of getting keys

* Rename with-keys to with-agent to better reflect what it does
* Make a new with-keys that does the same thing as with-agent, except
  that it passes $keys to keychain so that those keys are actually
  unlocked
* Divide between using with-keys and with-agent more-or-less
  reasonably
