Bruce, thanks for your reaction. I think you point to the responses of my
September-thread. But this is a new one and I see only my and now your
reaction in the mailinglist of january.

I will certainly do and use your hint. For the moment I stick to Grub 0.97
in order to make my Linux-life not more complicated then it already is.

I found out what I did wrong. By inserting a new partition in front of my  
lfs-partition, I thought the partitionnumber of the lfs-partition was  
increased by 1 so I changed Grub en fstab accordingly. But the number did  
not change! The number of the new partition was added at the end of the  
row. Changing Grub and fstab to what they were originally and LFS booted
