[ptxdist] [PATCH] [coreutils] Remove unused library libstdbuf.so
Is the libstdbuf.so from coreutils really used in some applets? The first install_copy in coreutils.targetinstall is to install this library to /usr/lib/coreutils/libstdbuf.so It seems to me, that no coreutils applet link itself to libstdbuf.so. I ran the following command from the packages/coreutils-8.2 directory where all applets should be installed. # find . -type f -perm -1 | xargs readelf -a | grep NEEDED | sort | uniq 0x0001 (NEEDED) Shared library: [libc.so.6] 0x0001 (NEEDED) Shared library: [libgcc_s.so.1] 0x0001 (NEEDED) Shared library: [libm.so.6] 0x0001 (NEEDED) Shared library: [librt.so.1] In my opinion, this should be removed at all.
