FYI, if you use gpg-agent or gnome-keyring instead of ssh-agent, it will
ask for the password interactively/graphically when it's needed the
first time.

I don't want to use a daemon that maintains state across hibernate.[1]
Does ssh-agent/gpg-agent/gnome-keyring have a "discard passphrase before
entering hibernate" feature?

Thanks,

Daniel

[1] With my current approach, the only state is the master connection,
and if I hibernate the server will drop it (due to TCP timeout).

You could run ssh-add -D after everything is connected, or in a
pm-suspend hook.  (I enable my screensaver before suspend/hibernate
and remove keys on screensaver activation:
