OMG! How large was the file at the end?

Isn't there a "low disk space" hint where information like this could go?
I can't find it so I might just have imagined such a thing exists. Anyway,
such a thing would be good to have. Care to write it?
It could also mention thinks like "make bootstrap-lean" (IIRC this target
makes gcc take less disk space during bootstrap) and it could be a new
home for the non-obsolete information from the
keep_chap5_and_chap6_separate hint (which aside from the /static chapter 5
process that has been included in LFS 4.0 also includes instructions how
to keep the _extracted_ sources on a different partition, e.g. a CDROM to
save even more space than you can save by having the tarballs stored
I am Pentium of Borg. Precision is futile.
Prepare to be approximated!
