busybox 1.22.0-18. /bin/ls is not a symlink to busybox in the initramfs. ls -la /bin/ls -rwxr-xr-x 1 0 0 2576 Jan 18 23:35 /bin/ls Running /bin/ls directly: /bin/ls -la /bin/ls -la: No such file or directory (klibc-utils ls) So I do not know if #823323 has a role here. busybox does use its built in ls as you can see, but not when the script is run.
