I copied the file into /share/MD0_DATA/ directory to avoid deletion upon device reboot.
I have rebooted the QNAP device and so far so good.
This is totally unsupported by QNAP so don't do it unless you know what you're doing! And please make a backup before!
What are the benefits? Among many much more utilities added, now I can use NSLOOKUP
The QNAP's original Busybox version v1.01 has the following functions:
addgroup, adduser, ash, awk, basename, bunzip2, busybox, bzcat, cat, chgrp, chmod, chown, chroot, chvt, clear, cmp, cp, crond, crontab, cut, date, dd, deallocvt, delgroup, deluser, df, dirname, dmesg, dos2unix, du, echo, egrep, env, expr, false, fdisk, fgrep, find, free, getty, grep, gunzip, gzip, halt, head, hexdump, hostname, hwclock, id, ifconfig, init, insmod, install, ip, kill, killall, klogd, linuxrc, ln, logger, login, ls, lsmod, md5sum, mkdir, mknod, mktemp, dprobe, more, mount, mv, nameif, netstat, openvt, passwd, pidof, ping, ping6, pivot_root, poweroff, ps, pwd, readlink, reboot, renice, reset, rm, rmdir, rmmod, route, sed, sh, sha1sum, sleep,sort, strings, swapoff, swapon, sync, sysctl, syslogd, tail, tar, tee, telnet, test, tftp, time, top, touch, tr, traceroute, true, tty, umount, uname, uniq, unix2dos, unzip, uptime, usleep, vi, wc, wget, which, whoami, xargs, yes, zcat
The added currrent stable version (v1.16) from Busybox.net has the following functions:
