it should imho just be better documented what to do, and where.

Options that imply changing BIOS settings are imho outside the scope of
FAI. FAI also has no easy way to learn how BIOS reconfigurations might
have changed the drive enumeration, and from my perspective, pulling
drives and re-inserting them into different slots is in the same realm
as is fiddling with BIOS settings.

This is imho also outside of the problem space of how to install a bood
loader, and it is, afaik, easy to do with the current state of the
software, too.

I have no objections here. The general problem seems to be that
installing a boot loader and arriving at a working system is not as
robust as might be desirable. At least I would be glad if I could solve
this problem first. ;-}


Kind regards,
