Regarding keys vs. host-based SSH, I see that host-based would be more
elegant, but would involve more configuration. What exactly are the
simplification gains you see? I just have a single cluster and naively I
would think dropping a script into /etc/profile.d on the login node
would be less work than re-configuring SSH for the login node and
multiple compute node images.
IMHO, it's really simply to setup hostbased SSH authentification:

This is more secure on Linux clusters, and you don't need to configure
users' SSH keys, so it requires less configuration for the sysadmin in the
long run.
