There shouldn't be.  I just separate the book instructions into "setup",
e.g. useradd, "build" binaries, and "finish", e.g. diddle /etc/fstab,
because it makes cloning simpler.  I'm a proponent of the KISS
philosophy.  To follow the book rigidly means doing it all in one
sitting, and I just can't do that!  So I cut and past into my build
template.  But I can understand why a Support Team wouldn't necessarily
want to examine every sort of script anyone could present.

This goes without saying, to the best of my ability and I was able to
build 6.1 this way.  My scripts begin back in Ch 4!

The 6.1 LFS has gcc-3.4.3.  I patched up to linux-2.6.18(.0).

How far back do you suppose?  Stage 2 pass 1 or Stage 1 pass 2?  I can
quite confidently rip either out and replace it with my scripts.
(UPMPMG; use package management, package management good)

I don't suppose you have any idea what kind of parameter error might
cause gcc's make to include it?  /tools/lib does have libssp.  I suppose
that's indicative, eh?  (Can't give you a listing at the moment, I'm on
a different twinned box also running 6.1.  But I can query my package
management on the other box to see which step added libssp.)

>2.6.18 kernel (i think) you said you built to begin the lfs build.

I see nothing in menuconfig which mentions stack protector in 2.6.18,
and before you ask, my kern-patch script does run oldconfig.  I grepped
the whole source directory for stack.chk.guard, nothing.

No fun.  1.4GHz P-3, 512MB.  Besides, as I wrote, I really want to have
a clean migration path.  Maybe 6.1 to 6.6 is too far a jump, but it
matched the HSR with the exception of kernel version.

Besides I rather think the LiveCD starts the NIC/network, mine doesn't
and I really don't want that.
