This is script what I use to start a ssh-agent (script placed in
/etc/profile.d) to hold (even between different login sessions) any keys
I load. I had to hack some X startup script to load /etc/profile.d
because it's not done by default.
The script works fine for me as I am the only physical user of my
computer with several accounts. On a real multiuser machine both you
and root user can acces keys loaded to your agent. There may be similar
problem with SSH tunnels.
Hope this helps.
