Thanks for this reminder
It is not actually that bad, I have done it twice from the scratch, once for a Cavium board (mips based) and once for x86.

The first time I did it, it took maybe two weeks working on and off with it, it was the more difficult thing since it required the cross-compiling suite to be built.
The x86-case was much easier, took less than a week.

Nowdays it is a lot easier than it usef to be; there are nice tools to help you with it, for example https://github.com/aakoskin/hammer which is a scripting set that makes your build repeatable; you just configure it and it downloads, patches, compiles and instslls the tarballs for you.
Working with hammer makes LFS almost like installing gentoo
