If I select rescue mode in GRUB, ssh is not run. I have to type start ssh to have it running. Can I made this be done automatically for me?
Typical situation is with broken graphics, when I need to login to the box remotely. Now, I have to type start ssh blindly first and hope.
When your system starts into the rescue mode, it uses the so called single user mode. This is runlevel 1. You'll find all programs which start here in /etc/rc1.d (starting with S).
You have to add ssh to runlevel 1. You can do this by making a symlink from /etc/init.d/ssh to /etc/rc1.d/S99ssh. The command update-rc.d assists you here. If you need a graphical program you can use bum (boot up manager).
