1719	'Chapter 6.61. Stripping Again' is wrong, --strip-all could be used on shared lib, not on kernel modules	Gilles Espinasse	lfs-book@…	"Chapter '6.61. Stripping Again' stable and devel LSF book state that:

""If disk space is very tight, the --strip-all option can be used on the binaries in /{,usr/}{bin,sbin} to gain several more megabytes. Do not use this option on libraries—they will be destroyed.""

--strip-all can't be used on kernel modules, but can be used on shared lib.

So the rule can't be the compact /tools/bin/find /{,usr/}{bin,lib,sbin} and need some rewrite.

I do
/tools/bin/find /lib /usr/lib /usr/share/rrdtool-* \
	-type f \( -name '*.so' -o -name '*.so[\.0-9]*' \) \
	-ls -exec /tools/bin/strip --strip-all {} \; #2>/dev/null

/tools/bin/find /{,s}bin /usr/{,s}bin /usr/local/{,s}bin \
	-type f \
	-exec /tools/bin/strip --strip-all {} \; 2>/dev/null

2>/dev/null allow to suppress the warning on .so scripts
-ls allow to see what files are stripped

Those stripping instructions work with LFS5.1 derivated build (using strip 2.15.90.0.3 20040415)
But it sometime fail with LFS6 derivated build (but using a different binutils with strip 2.16.91.0.5 ). In this case, it rarely fail during libc stripping with this log ( I had to repeat the strip script in a loop to reproduce the problem).

/tools/bin/find /lib /usr/lib /usr/share/rrdtool-* /install/initrd/lib \
	-type f \( -name '*.so' -o -name '*.so[\.0-9]*' \) \
	-ls -exec /tools/bin/strip --strip-all {} \; #2>/dev/null

...

So all files but libc-2.3.5.so are correclty stripped.
Any later attempt to strip again fail on libc-2.3.5.so the file look corrupted as I have to rebuild the lib to suppress the error.

I had supposed this is because a running binary can't be stripped
As find and strip are not statically build, they use shared lib.
Could it be the reason sometime strip fail to work on libc with signal 11?
Alernately, as it work on LFS5.1, it may be a bug in strip 2.16.91.0.5."	defect	closed	normal		Book	SVN	normal	wontfix	strip
