+Subject: [PATCH] skip copy nested binaries
+
+This script copies containerd, containerd-shim-runc-v2, ctr, runc,
+docker-init, rootlesskit, dockerd-rootless.sh, and dockerd-rootless-setuptool.sh
+into the `$dir` directory, which is unnecessary for OpenWrt. Moreover,
+if the host is missing any one of these files, cp will fail and cause an error.
+
+Fixes:
+```
+Copying nested executables into bundles/binary-daemon
+cp: cannot stat '': No such file or directory
+make[3]: *** [Makefile:166: /home/runner/work/Build/Build/openwrt/build_dir/target-x86_64_musl/dockerd-29.6.1/.built] Error 1
+```
