This config is far from perfect, was done in a hurry and since i was not
able to batter lilo into perfection i had to use boot=/dev/sda and do a
dd if=/dev/sda of=/dev/sdb bs=512 count=1
after running lilo
This config was tested and i was able to boot it removing the first drive.

I was not able to boot from an LVM 2 since lilo does not grok
device-mapper devices, btw lilo seems to need HDIO_GETGEO
syscall that is (was?) not available with device-mapper.

P.S. in case yoo wonder sd?1 is the server diagnostic partition
