Btw the "official Linux firmware"
https://git.kernel.org/?p=linux/kernel/git/firmware/linux-firmware.git;a=su…
introduced a dependency for the "rdfind" utility i think ~two
years ago (it was later made optional) for this code:
$verbose "Finding duplicate files"
rdfind -makesymlinks true -makeresultsfile false "$destdir"
>/dev/null
find "$destdir" -type l | while read -r l; do
target="$(realpath "$l")"
$verbose "Correcting path for $l"
ln -fs "$(realpath --relative-to="$(dirname "$(realpath -s
"$l")")" "$target")" "$l"
done
I proposed (because it really drove me mad, i have nothing to do
with Linux kernel stuff etc shall you think that)
(
cd "$destdir" && find . -type f | xargs cksum | sort | {
ls= lf=
while read s1 s2 f; do
s="$s1 $s2"
#$verbose $s $f
if [ "$s" = "$ls" ] && cmp "$lf"
"$f"; then
$verbose 'duplicate '"${lf##*/}" "${f#./*}"
rm -f "$f"
#ln -s "${lf#./*}" "${f#./*}"
ln -s "${lf##*/}" "${f#./*}"
else
ls=$s
lf=$f
fi
done
}
)
(as a draft, with only light testing, but it is not far from doing
it at maximum) which only uses POSIX default tools etc, but these
guys from very big companies (RedHat; the guy who did *that* is
from AMD) did not even respond, at least to that.
(At times i tried to get rid of rsync dependency of kernel
makefile officially, as that can also be done via plain shell
tools, they at least answered "what is wrong with rsync".)
Maybe because the patch also included
- compress="zstd --compress --quiet --stdout"
+ compress="zstd -T0 --ultra -22 --compress --quiet --stdout"
but that only brought the firmware into line with the normal Linux
kernel make zstd usage. I will never know.
I think what i am trying to say is that maybe "time is money" in
addition to anything else. (I never heard about rdfind though.
Btw its manual (it has one!) says
SEE ALSO
md5sum, sha1sum, find, symlinks
were cksum is a standard tool. So it is. Everyone its own
infrastructure, how large it is; you all only get the binary
updates anyway, my Linux distribution compiles from source; and
what the mesa library alone has grown in new dependencies that are
mostly never needed let alone at runtime, like YAML, that has been
done at release-tarball-creation time in the past. At least
here.)
