Thanks for this,
I compared a completed system of SVN-20200721 with a backup of the
temporary system and found that a few files from the temporary system
are not reinstalled on the final system as a side effect of the new way
of building LFS.
(1) Gawk hardlink.
/usr/bin/gawk-5.1.0 is still pointing to the temporary version of the
software. 'make install' does not replace this file if it already exists.
Possible fix is to just remove the link before rebuilding, or patch the
Makefile to always overwrite it.
I think
sed -i '/LN =/ s/$/ -f/' Makefile.in
can fix this. I've not tested yet.
(2) Perl.
Lots of files are not reinstalled, but are kept from the chapter 7 build
instead. Not sure if these should be removed, if they should have been
rebuilt in chapter 8, or if Perl is aware of these files and does not
reinstall them if they are already present.
-
/usr/lib/perl5/5.32/core_perl/{B,B.pm,Compress,Config.pod,Config_git.pl,Cwd.pm,...,<many
more>}
-
/usr/share/perl5/core_perl/{AnyDBM_File.pm,App,Archive,Attribute,AutoLoader.pm,AutoSplit.pm,...,<many
more>}
We can try 'rm -rf /usr/lib/perl5' at teh start of Chapter 8.
(3) Glibc header file (/usr/include/gnu/stubs-64.h).
Not sure about this one either. Could be that the build compares the
existing file and chooses not to overwrite it if it is unchanged. The
other 5 files in the same directory (like 'lib-names-64.h' and
'stubs.h') are re-created though.
We will need to wait for glibc-2.32 (due tomorrow) to check this.
(4) All Linux API Headers.
This is probably as intended in this new set up. But you may want to
clarify in the book that most (if not all) of these headers are kept on
the final system, even though they are installed during the
cross/temporary build phase.
Yes, the headers will not change between Chapters 7 and 10. I'm not sure
it is necessary to explain to the level of detail you suggest.
(5) A few symlinks are now created way before chapter 8.
This is not an issue for most LFS builders. But it is good to know that
these are left out on your system if you only capture the files built in
chapter 8 for package management.
- /bin/sh
- /lib64/ld-linux-x86-64.so.2
- /lib64/ld-lsb-x86-64.so.3
- /usr/bin/awk
- /usr/bin/cc
I'm used to making package archives from the builds that are now in
chapter 8, and if some files remain untouched in that phase, they are
not captured at all right now. So, if (2) and (3) are not bugs, then I
may have to change my capture mechanism to begin tracking files right
from the start of the build.
We really don't support package management directly in the book. I
think this type of information should go into a hint.
more_control_and_pkg_man.txt would be the most likely candidate if you
want to update it.
