I was reporting in another thread created before, but this one is better
named.

This, I solved.

This is bzip2? I'v done the same.

Here, I did almost the same, but had a problem, so, two more libraies to
be removed.

Not there yet.

This, I could remove all *.a

Not there yet.

If I have to restart, will remove, and will know the reason for the test
failure.

The same.

Agree

Will try to remember in util-linux.

Same.

They all did, for me.

Libz.a, I will reconsider in a second run, but libltdl.a, either I have
removed, or not yet arrived there.

I1ve quickly read you attachments, and some are what I did, but did no
extra sed's.

My first intention is to get a working system. After, being sure of
that, refine the necessary steps.

Now, some of my results.

Form bzip2 to coreutils, all static removed. Methods not so clean as
yours (Ken and Bruce). All available tests run and compared with
Bruce's. Including acl, after coreutils installed.

I've spent some time with e2fsprogs-1.42.1, because there is a problem
with my tools, and I had to build without
             --disable-libblkid      \
             --disable-libuuid       \
             --disable-uuidd         \
             --disable-fsck

Seems there was a problem with ncurses in tools, so I got a message when
building util linux in tools:

 configure: error: ncurses or ncursesw selected, but library not found
(--without-ncurses to disable)


I will finish if I can this build of LFS, then restart again, if I
cannot fix the duplicated porgs and libs of e2fsprogs and util linux.

Spent about hals of todays's time with ncurses; installed by the book
plus commands to remove *.a, wide and non-wide:

Only one failure in coreutils test: skip-duplicates.

Other packages tests, some better, some worse than Bruce's.
