 I don't quite understand what you're asking, but since you're another
user of the one true x86 bootloader (TM) I'll attempt to answer.

 Lilo stores a list of which blocks in the filesystem contain each
kernel it knows about.  The normal problem is that somebody recompiles a
kernel (keeping the name of the boot file the same) and doesn't rerun
lilo - the odds are that the filesystem will use different blocks to
store the new file.  Maybe your kernel is just called /boot/vmlinuz-lfs
and you've overwritten the old one ?  It's always a good idea to give
kernels a name including the version, and any extraversion you've added
(e.g. -1, -2, ... as you try different options - adding the extraversion
also puts modules into separate directories, which can be useful.

 If you're asking why version 5.0 of the lfs book doesn't mention this,
it's because it went to grub.  One of the advantages of grub is that it
can read the filesystem when it boots, so it can access the file by
