I use a DSA key. I start ssh-agent with its output redirected into 
a file with chmod 0600, and then source that file from any shell 
scripts that need it. I find it works great for cron jobs that need 
to use ssh. 

I basically start that instance of ssh-agent by hand whenever I have 
to reboot the machine, and then leave it running until the next reboot.
