FAI 2.4 upgrade problems

[Clemens Wehrmann]

I am having trouble debugging three problems with FAI 2.4.  I have not used
previous versions of FAI.

1.  Installation of bootloader fails
2.  Can't get shell after install or sysinfo (RETURN and Ctrl-C always
reboot).
3.  Can't ssh into the machine (Connection refused).

This makes it hard to debug.

I have tried the following class combinations:

   LILO MBR BOOT NET NETWORK SCSI

   LILO BOOT NET NETWORK SCSI

   GRUB MBR BOOT NET NETWORK SCSI

   GRUB BOOT NET NETWORK SCSI

each with the following combinations of disk_config/SCSI

disk_config sda
primary /boot
primary /boot-fai
primary /
...

disk_config sda
primary /boot
primary /
...

disk_config sda
primary /
...

------------

Looking at scripts/BOOT I notice that
  if LILO and MBR are defined, then lilo.conf contains boot=    (blank);
will lilo know this should be /dev/sda?
  GRUB doesn't respond to the MBR class.  Is this correct?

Greetings.
