Yes, it's supposed to do that.  BTW, lilo is quite fragile.  If a fsck 
changes the sectors, then you can't boot and there is no command line 
backup.  It's also much harder to recover from typos.

That's populated by udev: /etc/init.d/udev.  If it doesn't work, then 
you probably have a configuration issue.

Yes, you are supposed to set that to the value on your system.  We can't 
guess what you are going to use.
