This error code is using functions that are present in nolibc too. When using nolibc, the error is printed like: exec /runc.armel: errno=8 When using libc, as its perror() implementation translates the errno to a message, it is printed like: exec /runc.armel: exec format error Note that when using libc, the error is printed in the same way as before.
