Probably beyond the scope of LFS but this bit

  There is a command, grub-mkconfig that can write a configuration
file automatically.
  It uses a set of scripts in /etc/grub.d/ and will destroy any
customizations that you make.

is not strictly true and misses highlighting a useful finesse when
using the newer GRUB and
might thus be worth mentioning in BLFS.

You can put a file into /etc/grub.d, which has a low number, eg
06_known_good, into
which you can then put static menu entries that will then appear at
the top of the
dynamically created boot menu list.

If you use commercial distros that re-run grub-mkconfig when they add
new kernels,
this is one way to make sure you keep the one you last used as the
default until
you're happy with any new one.

If you considered using grub-mkconfig in LFS, this methodology might
be a good way to
instruct folk as to where to put a basic LFS boot stanza somewhere so
that it will always
appear, if they do want to run grub-mkconfig.
