In my system when building on top of the Ubuntu image, I've created an
additional generic user (with su credentials) that have different  
settings that
the ubuntu user, and that we use for generic tasks. I'd rather have  
direct ssh
access to this account rather than ssh as ubuntu and then do su.
So probably a startup script as suggested by Eric is still the best  
way to go at the
moment.

Indeed nice tool! In our case, at the moment we stick with the public  
keys
generated by EC2, on which we apply regular create/destroy rotations.

Sure. Is cloud-init/cloud.cfg ubuntu-specific or has it been taken up  
by other
distribs?

Thanks,
