no comment here, although I've personally preferred less instructions to
more where possible. (DESTDIR is not something I use) . I usually throw
away systems when it's time to upgrade though, or just install newer libs
over the old.

ah, I miss the bootscript days. I'll have to take a look, and find out what

When I designed my own multilib system, I had a few goals
- 32bit was not a essential part of my system. Only reason I have it is for
- I wanted /lib 64bit. Therefore, I used /lib/32 for 32bit libs (although
/lib32 would probably be a better book choice). [always bugged me that /lib
is normally the 32bit directory, especially since it is the default
- If possible, I would have liked to see multilib avaliable "after" building
lfs, but this is probably not feasable.
- I only install 32bit versions of glibc, zlib, ncurses, utillinux as
they're the only ones I actually needed for my 32bit uses. May be worth
reviewing who would be using 32bit, and what applications it would be
supporting. Multilib in the book would look nicer, if only
glibc/gcc/binutils had multilib tweaks. (Enough to compile 32bit software)

using .d folders has made scripted builds much nicer, and It seems tidier to
